Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]132 <li>Libxml2 exports Push (progressive) and Pull (blocking) type parser
133 interfaces for both XML and HTML.</li>
134 <li>Libxml2 can do DTD validation at parse time, using a parsed document

322 (<code>/home/user/myxml/libxml2 </code>)</li>
323 <li>configure the library using the "<code>--prefix</code>" switch,
324 specifying an installation subdirectory in
325 <code>/home/user/myxml</code>, e.g.
326 <p><code>./configure --prefix /home/user/myxml/xmlinst</code> {other
327 configuration options}</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]329 <li>now run <code>make</code> followed by <code>make install</code></li>
330 <li>At this point, the installation subdirectory contains the complete
331 "private" include files, library files and binary program files (e.g.
332 xmllint), located in
333 <p><code>/home/user/myxml/xmlinst/lib,
334 /home/user/myxml/xmlinst/include </code> and <code>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]337 <li>In order to use this "private" library, you should first add it to
338 the beginning of your default PATH (so that your own private program
339 files such as xmllint will be used instead of the normal system
340 ones). To do this, the Bash command would be
Daniel Veillard67952602006-01-05 15:29:44 +0000[diff] [blame]341 <p><code>export PATH=/home/user/myxml/xmlinst/bin:$PATH</code></p>
342 </li>
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]343 <li>Now suppose you have a program <code>test1.c</code> that you would
344 like to compile with your "private" library. Simply compile it using
345 the command
Daniel Veillard67952602006-01-05 15:29:44 +0000[diff] [blame]346 <p><code>gcc `xml2-config --cflags --libs` -o test test.c</code></p>
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]347 Note that, because your PATH has been set with <code>
348 /home/user/myxml/xmlinst/bin</code> at the beginning, the xml2-config
349 program which you just installed will be used instead of the system
350 default one, and this will <em>automatically</em> get the correct
351 libraries linked with your program.</li>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]465 <p>It is possible to validate documents which had not been validated at
466 initial parsing time or documents which have been built from scratch
467 using the API. Use the <a
468 href="http://xmlsoft.org/html/libxml-valid.html#xmlValidateDtd">xmlValidateDtd()</a>
469 function. It is also possible to simply add a DTD to an existing
470 document:</p>
Daniel Veillardb8cfbd12001-10-25 10:53:28 +0000[diff] [blame]471 <pre>xmlDocPtr doc; /* your existing document */
Daniel Veillard0b28e882002-07-24 23:47:05 +0000[diff] [blame]472xmlDtdPtr dtd = xmlParseDTD(NULL, filename_of_dtd); /* parse the DTD */
473
Daniel Veillardb8cfbd12001-10-25 10:53:28 +0000[diff] [blame]474 dtd-&gt;name = xmlStrDup((xmlChar*)"root_name"); /* use the given root */
475
476 doc-&gt;intSubset = dtd;
477 if (doc-&gt;children == NULL) xmlAddChild((xmlNodePtr)doc, (xmlNodePtr)dtd);
478 else xmlAddPrevSibling(doc-&gt;children, (xmlNodePtr)dtd);
479 </pre>

William M. Brack43a87292007-02-15 20:41:02 +0000[diff] [blame]481 <li><em>So what is this funky "xmlChar" used all the time?</em>
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]482 <p>It is a null terminated sequence of utf-8 characters. And only utf-8!
483 You need to convert strings encoded in different ways to utf-8 before
484 passing them to the API. This can be accomplished with the iconv library
485 for instance.</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]527<p>Well, bugs or missing features are always possible, and I will make a
528point of fixing them in a timely fashion. The best way to report a bug is to
529use the <a href="http://bugzilla.gnome.org/buglist.cgi?product=libxml2">Gnome
530bug tracking database</a> (make sure to use the "libxml2" module name). I
531look at reports there regularly and it's good to have a reminder when a bug
532is still open. Be sure to specify that the bug is for the package libxml2.</p>

2091 <li>Increased the library modularity, far more options can be stripped out,
2092 a --with-minimum configuration will weight around 160KBytes</li>
2093 <li>Use per parser and per document dictionnary, allocate names and small
2094 text nodes from the dictionnary</li>
2095 <li>Switch to a SAX2 like parser rewrote most of the XML parser core,
2096 provides namespace resolution and defaulted attributes, minimize memory
2097 allocations and copies, namespace checking and specific error handling,
2098 immutable buffers, make predefined entities static structures, etc...</li>
2099 <li>rewrote all the error handling in the library, all errors can be
2100 intercepted at a structured level, with precise information

3226a tag is empty (no content), a single tag can serve as both the opening and
3227closing tag if it ends with <code>/&gt;</code> rather than with
3228<code>&gt;</code>. Note that, for example, the image tag has no content (just
3229an attribute) and is closed by ending the tag with <code>/&gt;</code>.</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]3374<p>The Python module is called libxml2; parseFile is the equivalent of
3375xmlParseFile (most of the bindings are automatically generated, and the xml
3376prefix is removed and the casing convention are kept). All node seen at the
3377binding level share the same subset of accessors:</p>

3388
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]3389<p>Also note the need to explicitly deallocate documents with freeDoc() .
3390Reference counting for libxml2 trees would need quite a lot of work to
3391function properly, and rather than risk memory leaks if not implemented
3392correctly it sounds safer to have an explicit function to free a tree. The
3393wrapper python objects like doc, root or child are them automatically garbage
3394collected.</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]3426<p>Contexts like nodes are defined as class and the libxml2 wrappers maps the
3427C function interfaces in terms of objects method as much as possible. The
3428best to get a complete view of what methods are supported is to look at the

3441
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]3442<p>The context is created with a special call based on the
3443xmlCreatePushParser() from the C library. The first argument is an optional
3444SAX callback object, then the initial set of data, the length and the name of
3445the resource in case URI-References need to be computed by the parser.</p>

3589<pre>#memory debug specific
3590libxml2.cleanupParser()
3591if libxml2.debugMemory(1) == 0:
3592 print "OK"
3593else:

3596
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]3597<p>Those activate the memory debugging interface of libxml2 where all
3598allocated block in the library are tracked. The prologue then cleans up the
3599library state and checks that all allocated memory has been freed. If not it
3600calls dumpMemory() which saves that list in a <code>.memdump</code> file.</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]3685<p>Sometimes the DOM tree output is just too large to fit reasonably into
3686memory. In that case (and if you don't expect to save back the XML document
3687loaded using libxml), it's better to use the SAX interface of libxml. SAX is
3688a <strong>callback-based interface</strong> to the parser. Before parsing,
3689the application layer registers a customized set of callbacks which are
3690called by the library as it progresses through the XML input.</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]3766<p>DTD is the acronym for Document Type Definition. This is a description of
3767the content for a family of XML files. This is part of the XML 1.0
3768specification, and allows one to describe and verify that a given document
3769instance conforms to the set of rules detailing its structure and content.</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]3771<p>Validation is the process of checking a document against a DTD (more

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]3774<p>The validation process and building DTDs are the two most difficult parts
3775of the XML life cycle. Briefly a DTD defines all the possible elements to be
3776found within your document, what is the formal shape of your document tree
3777(by defining the allowed content of an element; either text, a regular
3778expression for the allowed list of children, or mixed content i.e. both text
3779and children). The DTD also defines the valid attributes for all elements and
3780the types of those attributes.</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]3799<p>Writing DTDs can be done in many ways. The rules to build them if you need
3800something permanent or something which can evolve over time can be radically
3801different. Really complex DTDs like DocBook ones are flexible but quite
3802harder to design. I will just focus on DTDs for a formats with a fixed simple
3803structure. It is just a set of basic rules, and definitely not exhaustive nor
3804usable for complex DTD design.</p>

4069of a number of things:</p>
Daniel Veillardb8cfbd12001-10-25 10:53:28 +0000[diff] [blame]4070<ul>
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4071 <li>the parser itself should work in a fixed amount of memory, except for
4072 information maintained about the stacks of names and entities locations.
4073 The I/O and encoding handlers will probably account for a few KBytes.
4074 This is true for both the XML and HTML parser (though the HTML parser
4075 need more state).</li>
4076 <li>If you are generating the DOM tree then memory requirements will grow
4077 nearly linear with the size of the data. In general for a balanced
4078 textual document the internal memory requirement is about 4 times the
4079 size of the UTF8 serialization of this document (example the XML-1.0
4080 recommendation is a bit more of 150KBytes and takes 650KBytes of main
4081 memory when parsed). Validation will add a amount of memory required for
4082 maintaining the external Dtd state which should be linear with the
4083 complexity of the content model defined by the Dtd</li>
4084 <li>If you need to work with fixed memory requirements or don't need the
4085 full DOM tree then using the <a href="xmlreader.html">xmlReader
4086 interface</a> is probably the best way to proceed, it still allows to
4087 validate or operate on subset of the tree if needed.</li>
4088 <li>If you don't care about the advanced features of libxml2 like
4089 validation, DOM, XPath or XPointer, don't use entities, need to work with
4090 fixed memory requirements, and try to get the fastest parsing possible
4091 then the SAX interface should be used, but it has known restrictions.</li>

4096
4097<p>You may encounter that your process using libxml2 does not have a
4098reduced memory usage although you freed the trees. This is because
4099libxml2 allocates memory in a number of small chunks. When freeing one
4100of those chunks, the OS may decide that giving this little memory back
4101to the kernel will cause too much overhead and delay the operation. As
4102all chunks are this small, they get actually freed but not returned to
4103the kernel. On systems using glibc, there is a function call
4104"malloc_trim" from malloc.h which does this missing operation (note that
4105it is allowed to fail). Thus, after freeing your tree you may simply try
4106"malloc_trim(0);" to really get the memory back. If your OS does not
4107provide malloc_trim, try searching for a similar function.</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4138<p>XML was designed from the start to allow the support of any character set
4139by using Unicode. Any conformant XML parser has to support the UTF-8 and
4140UTF-16 default encodings which can both express the full unicode ranges. UTF8
4141is a variable length encoding whose greatest points are to reuse the same
4142encoding for ASCII and to save space for Western encodings, but it is a bit
4143more complex to handle in practice. UTF-16 use 2 bytes per character (and
4144sometimes combines two pairs), it makes implementation easier, but looks a
4145bit overkill for Western languages encoding. Moreover the XML specification
4146allows the document to be encoded in other encodings at the condition that
4147they are clearly labeled as such. For example the following is a wellformed
4148XML document encoded in ISO-8859-1 and using accentuated letters that we
4149French like for both markup and content:</p>

4162
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4163<p>Another very important point is that the whole libxml2 API, with the

4182
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4183<p>One of the core decisions was to force all documents to be converted to a
4184default internal encoding, and that encoding to be UTF-8, here are the
4185rationales for those choices:</p>
Daniel Veillardb8cfbd12001-10-25 10:53:28 +0000[diff] [blame]4186<ul>
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4187 <li>keeping the native encoding in the internal form would force the libxml
4188 users (or the code associated) to be fully aware of the encoding of the
4189 original document, for examples when adding a text node to a document,
4190 the content would have to be provided in the document encoding, i.e. the
4191 client code would have to check it before hand, make sure it's conformant
4192 to the encoding, etc ... Very hard in practice, though in some specific
4193 cases this may make sense.</li>
4194 <li>the second decision was which encoding. From the XML spec only UTF8 and
4195 UTF16 really makes sense as being the two only encodings for which there
4196 is mandatory support. UCS-4 (32 bits fixed size encoding) could be
4197 considered an intelligent choice too since it's a direct Unicode mapping
4198 support. I selected UTF-8 on the basis of efficiency and compatibility
4199 with surrounding software:
Daniel Veillardb8cfbd12001-10-25 10:53:28 +0000[diff] [blame]4200 <ul>
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4201 <li>UTF-8 while a bit more complex to convert from/to (i.e. slightly
4202 more costly to import and export CPU wise) is also far more compact
4203 than UTF-16 (and UCS-4) for a majority of the documents I see it used
4204 for right now (RPM RDF catalogs, advogato data, various configuration
4205 file formats, etc.) and the key point for today's computer
4206 architecture is efficient uses of caches. If one nearly double the
4207 memory requirement to store the same amount of data, this will trash
4208 caches (main memory/external caches/internal caches) and my take is
4209 that this harms the system far more than the CPU requirements needed
4210 for the conversion to UTF-8</li>
4211 <li>Most of libxml2 version 1 users were using it with straight ASCII
4212 most of the time, doing the conversion with an internal encoding
4213 requiring all their code to be rewritten was a serious show-stopper
4214 for using UTF-16 or UCS-4.</li>
4215 <li>UTF-8 is being used as the de-facto internal encoding standard for
4216 related code like the <a href="http://www.pango.org/">pango</a>
4217 upcoming Gnome text widget, and a lot of Unix code (yet another place
4218 where Unix programmer base takes a different approach from Microsoft
4219 - they are using UTF-16)</li>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4226 <li>xmlChar, the libxml2 data type is a byte, those bytes must be assembled
4227 as UTF-8 valid strings. The proper way to terminate an xmlChar * string
4228 is simply to append 0 byte, as usual.</li>
4229 <li>One just need to make sure that when using chars outside the ASCII set,
4230 the values has been properly converted to UTF-8</li>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4235<p>Let's describe how all this works within libxml, basically the I18N
4236(internationalization) support get triggered only during I/O operation, i.e.
4237when reading a document or saving one. Let's look first at the reading
4238sequence:</p>
Daniel Veillardb8cfbd12001-10-25 10:53:28 +0000[diff] [blame]4239<ol>
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4240 <li>when a document is processed, we usually don't know the encoding, a
4241 simple heuristic allows to detect UTF-16 and UCS-4 from encodings where
4242 the ASCII range (0-0x7F) maps with ASCII</li>
4243 <li>the xml declaration if available is parsed, including the encoding
4244 declaration. At that point, if the autodetected encoding is different
4245 from the one declared a call to xmlSwitchEncoding() is issued.</li>
4246 <li>If there is no encoding declaration, then the input has to be in either
4247 UTF-8 or UTF-16, if it is not then at some point when processing the
4248 input, the converter/checker of UTF-8 form will raise an encoding error.
4249 You may end-up with a garbled document, or no document at all ! Example:
Daniel Veillardb8cfbd12001-10-25 10:53:28 +0000[diff] [blame]4250 <pre>~/XML -&gt; ./xmllint err.xml
4251err.xml:1: error: Input is not proper UTF-8, indicate encoding !

4257 </li>
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4258 <li>xmlSwitchEncoding() does an encoding name lookup, canonicalize it, and
4259 then search the default registered encoding converters for that encoding.
4260 If it's not within the default set and iconv() support has been compiled
4261 it, it will ask iconv for such an encoder. If this fails then the parser
4262 will report an error and stops processing:
Daniel Veillardb8cfbd12001-10-25 10:53:28 +0000[diff] [blame]4263 <pre>~/XML -&gt; ./xmllint err2.xml

4265&lt;?xml version="1.0" encoding="UnsupportedEnc"?&gt;

4267 </li>
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4268 <li>From that point the encoder processes progressively the input (it is
4269 plugged as a front-end to the I/O module) for that entity. It captures
4270 and converts on-the-fly the document to be parsed to UTF-8. The parser
4271 itself just does UTF-8 checking of this input and process it
4272 transparently. The only difference is that the encoding information has
4273 been added to the parsing context (more precisely to the input
4274 corresponding to this entity).</li>
4275 <li>The result (when using DOM) is an internal form completely in UTF-8
4276 with just an encoding information on the document node.</li>

4278
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4279<p>Ok then what happens when saving the document (assuming you
4280collected/built an xmlDoc DOM like structure) ? It depends on the function
4281called, xmlSaveFile() will just try to save in the original encoding, while
4282xmlSaveFileTo() and xmlSaveFileEnc() can optionally save to a given
4283encoding:</p>
Daniel Veillardb8cfbd12001-10-25 10:53:28 +0000[diff] [blame]4284<ol>
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4285 <li>if no encoding is given, libxml2 will look for an encoding value
4286 associated to the document and if it exists will try to save to that
4287 encoding,
Daniel Veillardb8cfbd12001-10-25 10:53:28 +0000[diff] [blame]4288 <p>otherwise everything is written in the internal form, i.e. UTF-8</p>
4289 </li>
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4290 <li>so if an encoding was specified, either at the API level or on the
4291 document, libxml2 will again canonicalize the encoding name, lookup for a
4292 converter in the registered set or through iconv. If not found the
4293 function will return an error code</li>
4294 <li>the converter is placed before the I/O buffer layer, as another kind of
4295 buffer, then libxml2 will simply push the UTF-8 serialization to through
4296 that buffer, which will then progressively be converted and pushed onto
4297 the I/O layer.</li>
4298 <li>It is possible that the converter code fails on some input, for example
4299 trying to push an UTF-8 encoded Chinese character through the UTF-8 to
4300 ISO-8859-1 converter won't work. Since the encoders are progressive they
4301 will just report the error and the number of bytes converted, at that
4302 point libxml2 will decode the offending character, remove it from the
4303 buffer and replace it with the associated charRef encoding &amp;#123; and
4304 resume the conversion. This guarantees that any document will be saved
4305 without losses (except for markup names where this is not legal, this is
4306 a problem in the current version, in practice avoid using non-ascii
4307 characters for tag or attribute names). A special "ascii" encoding name
4308 is used to save documents to a pure ascii form can be used when
4309 portability is really crucial</li>

4323processing. Looking up and modifying the content encoding is a bit more

4325so a couple of functions htmlGetMetaEncoding() and htmlSetMetaEncoding() have
4326been provided. The parser also attempts to switch encoding on the fly when
4327detecting such a tag on input. Except for that the processing is the same
4328(and again reuses the same code).</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4359<p>From 2.2.3, libxml2 has support to register encoding names aliases. The
4360goal is to be able to parse document whose encoding is supported but where
4361the name differs (for example from the default set of names accepted by
4362iconv). The following functions allow to register and handle new aliases for
4363existing encodings. Once registered libxml2 will automatically lookup the
4364aliases when handling a document:</p>

4402 (files) based on their PUBLIC and SYSTEM identifiers. The default loader
4403 don't look at the public identifier since libxml2 do not maintain a
4404 catalog. You can redefine you own entity loader by using
4405 <code>xmlGetExternalEntityLoader()</code> and

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4410 provides buffering and is also a placeholder where the encoding

4412 <li>Output I/O buffers are similar to the Input ones and fulfill similar

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4424 <li>The default entity loader calls <code>xmlNewInputFromFile()</code> with
4425 the parsing context and the URI string.</li>
4426 <li>the URI string is checked against the existing registered handlers
4427 using their match() callback function, if the HTTP module was compiled
4428 in, it is registered and its match() function will succeeds</li>
4429 <li>the open() function of the handler is called and if successful will
4430 return an I/O Input buffer</li>
4431 <li>the parser will the start reading from this buffer and progressively
4432 fetch information from the resource, calling the read() function of the
4433 handler until the resource is exhausted</li>
4434 <li>if an encoding change is detected it will be installed on the input
4435 buffer, providing buffering and efficient use of the conversion
4436 routines</li>
4437 <li>once the parser has finished, the close() function of the handler is
4438 called once and the Input buffer and associated resources are
4439 deallocated.</li>

4446
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4447<p>All the buffer manipulation handling is done using the
4448<code>xmlBuffer</code> type define in <code><a
4449href="http://xmlsoft.org/html/libxml-tree.html">tree.h</a> </code>which is a
4450resizable memory buffer. The buffer allocation strategy can be selected to be
4451either best-fit or use an exponential doubling one (CPU vs. memory use
4452trade-off). The values are <code>XML_BUFFER_ALLOC_EXACT</code> and
4453<code>XML_BUFFER_ALLOC_DOUBLEIT</code>, and can be set individually or on a
4454system wide basis using <code>xmlBufferSetAllocationScheme()</code>. A number
4455of functions allows to manipulate buffers with names starting with the
4456<code>xmlBuffer...</code> prefix.</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4574<p>What is a catalog? Basically it's a lookup mechanism used when an entity
4575(a file or a remote resource) references another entity. The catalog lookup
4576is inserted between the moment the reference is recognized by the software
4577(XML parser, stylesheet processing, or even images referenced for inclusion
4578in a rendering) and the time where loading that resource is actually
4579started.</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4622<p>In a normal environment libxml2 will by default check the presence of a
4623catalog in /etc/xml/catalog, and assuming it has been correctly populated,
4624the processing is completely transparent to the document user. To take a
4625concrete example, suppose you are authoring a DocBook document, this one
4626starts with the following DOCTYPE definition:</p>

4633DocBk XML V3.1.4//EN" and the system identifier
4634"http://nwalsh.com/docbook/xml/3.1.4/db3xml.dtd", and if these entities have
4635been installed on your system and the catalogs actually point to them, libxml
4636will fetch them from the local disk.</p>

4723the base URI unavailable and the the "title.xml" entity cannot be loaded.
4724Setting up the debug environment variable allows to detect that an attempt is
4725made to load the <code>/etc/xml/catalog</code> but since it's not present the
4726resolution fails.</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4773<p>Basically XML Catalogs are XML files, you can either use XML tools to
4774manage them or use <strong>xmlcatalog</strong> for this. The basic step is
4775to create a catalog the -create option provide this facility:</p>

4782
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4783<p>By default xmlcatalog does not overwrite the original catalog and save the
4784result on the standard output, this can be overridden using the -noout
4785option. The <code>-add</code> command allows to add entries in the
4786catalog:</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4824<p>First, and like for every other module of libxml, there is an
4825automatically generated <a href="html/libxml-catalog.html">API page for

Daniel Veillardb8cfbd12001-10-25 10:53:28 +0000[diff] [blame]4827
4828<p>The header for the catalog interfaces should be included as:</p>

4830
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4831<p>The API is voluntarily kept very simple. First it is not obvious that
4832applications really need access to it since it is the default behaviour of
4833libxml2 (Note: it is possible to completely override libxml2 default catalog

Daniel Veillard8a469172003-06-12 16:05:07 +0000[diff] [blame]4837<p>Basically libxml2 support 2 catalog lists:</p>

4839 <li>the default one, global shared by all the application</li>
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4840 <li>a per-document catalog, this one is built if the document uses the
4841 <code>oasis-xml-catalog</code> PIs to specify its own catalog list, it is
4842 associated to the parser context and destroyed when the parsing context
4843 is destroyed.</li>
Daniel Veillardb8cfbd12001-10-25 10:53:28 +0000[diff] [blame]4844</ul>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4850<p>xmlInitializeCatalog(), xmlLoadCatalog() and xmlLoadCatalogs() should be
4851used at startup to initialize the catalog, if the catalog should be
4852initialized with specific values xmlLoadCatalog() or xmlLoadCatalogs()
4853should be called before xmlInitializeCatalog() which would otherwise do a
4854default initialization first.</p>

4860
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4861<p>The XML Catalog spec requires the possibility to select default
4862preferences between public and system delegation,
4863xmlCatalogSetDefaultPrefer() allows this, xmlCatalogSetDefaults() and
4864xmlCatalogGetDefaults() allow to control if XML Catalogs resolution should
4865be forbidden, allowed for global catalog, for document catalog or both, the
4866default is to allow both.</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]4868<p>And of course xmlCatalogSetDebug() allows to generate debug messages

4874and xmlCatalogResolveURI() are relatively explicit if you read the XML
4875Catalog specification they correspond to section 7 algorithms, they should
4876also work if you have loaded an SGML catalog with a simplified semantic.</p>

5021
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]5022<p>The tree-building interface makes the parser memory-hungry, first loading
5023the document in memory and then building the tree itself. Reading a document
5024without building the tree is possible using the SAX interfaces (see SAX.h and
5025<a href="http://www.daa.com.au/~james/gnome/xml-sax/xml-sax.html">James
5026Henstridge's documentation</a>). Note also that the push interface can be
5027limited to SAX: just use the two first arguments of
5028<code>xmlCreatePushParserCtxt()</code>.</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]5191<p>One of the problems related to entities is that you may want the parser to
5192substitute an entity's content so that you can see the replacement text in
5193your application. Or you may prefer to keep entity references as such in the
5194content to be able to save the document back without losing this usually
5195precious information (if the user went through the pain of explicitly
5196defining entities, he may have a a rather negative attitude if you blindly
5197substitute them as saving time). The <a

5199function allows you to check and change the behaviour, which is to not

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]5252<p>I suggest that people using libxml2 use a namespace, and declare it in the
5253root element of their document as the default namespace. Then they don't need
5254to use the prefix in the content but we will have a basis for future semantic
5255refinement and merging of data from different sources. This doesn't increase
5256the size of the XML output significantly, but significantly increases its
5257value in the long-term. Example:</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]5263<p>The namespace value has to be an absolute URL, but the URL doesn't have to
5264point to any existing resource on the Web. It will bind all the element and
5265attributes with that URL. I suggest to use an URL within a domain you
5266control, and that the URL should contain some kind of version information if
5267possible. For example, <code>"http://www.gnome.org/gnumeric/1.0/"</code> is a
5268good namespace scheme.</p>

Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]5270<p>Then when you load a file, make sure that a namespace carrying the
5271version-independent prefix is installed on the root element of your document,
5272and if the version information don't match something you know, warn the user
5273and be liberal in what you accept as the input. Also do *not* try to base
5274namespace checking on the prefix value. &lt;foo:text&gt; may be exactly the
5275same as &lt;bar:text&gt; in another document. What really matters is the URI
5276associated with the element or the attribute, not the prefix string (which is
5277just a shortcut for the full URI). In libxml, element and attributes have an
5278<code>ns</code> field pointing to an xmlNs structure detailing the namespace
5279prefix and its URI.</p>

5290I will try to make sure that using namespaces won't break validity checking,
5291so even if you plan to use or currently are using validation I strongly
5292suggest adding namespaces to your document. A default namespace scheme
5293<code>xmlns="http://...."</code> should not break validity even on less
5294flexible parsers. Using namespaces to mix and differentiate content coming
5295from multiple DTDs will certainly break current validation schemes. To check

5312 programming model and simplifying the task of the DOM implementors.</li>
5313 <li>better conformances to the XML specification, for example version 1.x
5314 had an heuristic to try to detect ignorable white spaces. As a result the
5315 SAX event generated were ignorableWhitespace() while the spec requires
5316 character() in that case. This also mean that a number of DOM node
5317 containing blank text may populate the DOM tree which were not present

5330 is now -lxml2 . There is a new xml2-config script which should be used to
5331 select the right parameters libxml2</li>
5332 <li>Node <strong>childs</strong> field has been renamed
5333 <strong>children</strong> so s/childs/children/g should be applied
5334 (probability of having "childs" anywhere else is close to 0+</li>
5335 <li>The document don't have anymore a <strong>root</strong> element it has
5336 been replaced by <strong>children</strong> and usually you will get a
5337 list of element here. For example a Dtd element for the internal subset
5338 and it's declaration may be found in that list, as well as processing
5339 instructions or comments found before or after the document root element.
5340 Use <strong>xmlDocGetRootElement(doc)</strong> to get the root element of
5341 a document. Alternatively if you are sure to not reference DTDs nor have
5342 PIs or comments before or after the root element
5343 s/-&gt;root/-&gt;children/g will probably do it.</li>
5344 <li>The white space issue, this one is more complex, unless special case of
5345 validating parsing, the line breaks and spaces usually used for indenting
5346 and formatting the document content becomes significant. So they are
5347 reported by SAX and if your using the DOM tree, corresponding nodes are

5352 relying on a special (and possibly broken) set of heuristics of
5353 libxml to detect ignorable blanks. Don't complain if it breaks or
5354 make your application not 100% clean w.r.t. to it's input.</li>
5355 <li>the Right Way: change you code to accept possibly insignificant
5356 blanks characters, or have your tree populated with weird blank text

Daniel Veillard14fff061999-06-22 21:49:07 +0000[diff] [blame]5588<ul>
Daniel Veillardf781dba2006-06-09 13:34:49 +0000[diff] [blame]5589 <li>Usually a recursive parsing style is the more convenient one: XML data
5590 is by nature subject to repetitive constructs and usually exhibits highly
5591 structured patterns.</li>
5592 <li>The two arguments of type <em>xmlDocPtr</em> and <em>xmlNsPtr</em>,
5593 i.e. the pointer to the global XML document and the namespace reserved to
5594 the application. Document wide information are needed for example to
5595 decode entities and it's a good coding practice to define a namespace for
5596 your application set of data and test that the element and attributes
5597 you're analyzing actually pertains to your application space. This is
5598 done by a simple equality test (cur-&gt;ns == ns).</li>
5599 <li>To retrieve text and attributes value, you can use the function
5600 <em>xmlNodeListGetString</em> to gather all the text and entity reference
5601 nodes generated by the DOM output and produce an single text string.</li>
