Daniel Veillard | f781dba | 2006-06-09 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 |

| 340 | ones). To do this, the Bash command would be |
Daniel Veillard | 6795260 | 2006-01-05 15:29:44 +0000 | [diff] [blame] | 341 | <p><code>export PATH=/home/user/myxml/xmlinst/bin:$PATH</code></p> |

Daniel Veillard | f781dba | 2006-06-09 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 Veillard | 6795260 | 2006-01-05 15:29:44 +0000 | [diff] [blame] | 346 | <p><code>gcc `xml2-config --cflags --libs` -o test test.c</code></p> |
Daniel Veillard | f781dba | 2006-06-09 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 |

| 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 |
| 2101 | available.</li> |
| 2102 | <li>New simpler and more generic XML and HTML parser APIs, allowing to |

| 2105 | <li>Similar new APIs for the xmlReader, for options and reuse, provided new |
| 2106 | functions to access content as const strings, use them for Python |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 3685 | <p>Sometimes the DOM tree output is just too large to fit reasonably into |
| 3686 | memory. In that case (and if you don't expect to save back the XML document |
| 3687 | loaded using libxml), it's better to use the SAX interface of libxml. SAX is |
| 3688 | a <strong>callback-based interface</strong> to the parser. Before parsing, |
| 3689 | the application layer registers a customized set of callbacks which are |
| 3690 | called by the library as it progresses through the XML input.</p> |

| 3775 | of the XML life cycle. Briefly a DTD defines all the possible elements to be |
| 3776 | found 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 |
| 3778 | expression for the allowed list of children, or mixed content i.e. both text |
| 3779 | and children). The DTD also defines the valid attributes for all elements and |
| 3780 | the types of those attributes.</p> |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 4058 | <p>I used to use a commercial tool to debug libxml2 memory problems but after |
| 4059 | noticing that it was not detecting memory leaks that simple mechanism was |
| 4060 | used and proved extremely efficient until now. Lately I have also used <a |
| 4061 | href="http://developer.kde.org/~sewardj/">valgrind</a> with quite some |
| 4062 | success, it is tied to the i386 architecture since it works by emulating the |
| 4063 | processor and instruction set, it is slow but extremely efficient, i.e. it |
| 4064 | spot memory usage errors in a very precise way.</p> |

| 4067 | |
Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 4068 | <p>How much libxml2 memory require ? It's hard to tell in average it depends |
| 4069 | of a number of things:</p> |
Daniel Veillard | b8cfbd1 | 2001-10-25 10:53:28 +0000 | [diff] [blame] | 4070 | <ul> |
Daniel Veillard | f781dba | 2006-06-09 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 |
| 4098 | reduced memory usage although you freed the trees. This is because |
| 4099 | libxml2 allocates memory in a number of small chunks. When freeing one |
| 4100 | of those chunks, the OS may decide that giving this little memory back |
| 4101 | to the kernel will cause too much overhead and delay the operation. As |
| 4102 | all chunks are this small, they get actually freed but not returned to |
| 4103 | the kernel. On systems using glibc, there is a function call |
| 4104 | "malloc_trim" from malloc.h which does this missing operation (note that |
| 4105 | it 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 |
| 4107 | provide malloc_trim, try searching for a similar function.</p> |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 4138 | <p>XML was designed from the start to allow the support of any character set |
| 4139 | by using Unicode. Any conformant XML parser has to support the UTF-8 and |
| 4140 | UTF-16 default encodings which can both express the full unicode ranges. UTF8 |
| 4141 | is a variable length encoding whose greatest points are to reuse the same |
| 4142 | encoding for ASCII and to save space for Western encodings, but it is a bit |
| 4143 | more complex to handle in practice. UTF-16 use 2 bytes per character (and |
| 4144 | sometimes combines two pairs), it makes implementation easier, but looks a |
| 4145 | bit overkill for Western languages encoding. Moreover the XML specification |
| 4146 | allows the document to be encoded in other encodings at the condition that |
| 4147 | they are clearly labeled as such. For example the following is a wellformed |
| 4148 | XML document encoded in ISO-8859-1 and using accentuated letters that we |
| 4149 | French like for both markup and content:</p> |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 4163 | <p>Another very important point is that the whole libxml2 API, with the |

| 4182 | |
Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 4183 | <p>One of the core decisions was to force all documents to be converted to a |
| 4184 | default internal encoding, and that encoding to be UTF-8, here are the |
| 4185 | rationales for those choices:</p> |
Daniel Veillard | b8cfbd1 | 2001-10-25 10:53:28 +0000 | [diff] [blame] | 4186 | <ul> |
Daniel Veillard | f781dba | 2006-06-09 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 Veillard | b8cfbd1 | 2001-10-25 10:53:28 +0000 | [diff] [blame] | 4200 | <ul> |
Daniel Veillard | f781dba | 2006-06-09 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> |

| 4236 | (internationalization) support get triggered only during I/O operation, i.e. |
| 4237 | when reading a document or saving one. Let's look first at the reading |
| 4238 | sequence:</p> |

Daniel Veillard | f781dba | 2006-06-09 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: |

| 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 Veillard | f781dba | 2006-06-09 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 |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 4279 | <p>Ok then what happens when saving the document (assuming you |
| 4280 | collected/built an xmlDoc DOM like structure) ? It depends on the function |
| 4281 | called, xmlSaveFile() will just try to save in the original encoding, while |
| 4282 | xmlSaveFileTo() and xmlSaveFileEnc() can optionally save to a given |
| 4283 | encoding:</p> |
Daniel Veillard | b8cfbd1 | 2001-10-25 10:53:28 +0000 | [diff] [blame] | 4284 | <ol> |
Daniel Veillard | f781dba | 2006-06-09 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 Veillard | b8cfbd1 | 2001-10-25 10:53:28 +0000 | [diff] [blame] | 4288 | <p>otherwise everything is written in the internal form, i.e. UTF-8</p> |
| 4289 | </li> |
Daniel Veillard | f781dba | 2006-06-09 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 |

| 4303 | buffer and replace it with the associated charRef encoding &#123; and |
| 4304 | resume the conversion. This guarantees that any document will be saved |

| 4625 | concrete example, suppose you are authoring a DocBook document, this one |
| 4626 | starts with the following DOCTYPE definition:</p> |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 4631 | <p>When validating the document with libxml, the catalog will be |

| 4634 | "http://nwalsh.com/docbook/xml/3.1.4/db3xml.dtd", and if these entities have |

| 4833 | libxml2 (Note: it is possible to completely override libxml2 default catalog |
| 4834 | by using <a href="html/libxml-parser.html">xmlSetExternalEntityLoader</a> to |
| 4835 | plug an application specific resolver).</p> |

Daniel Veillard | 8a46917 | 2003-06-12 16:05:07 +0000 | [diff] [blame] | 4837 | <p>Basically libxml2 support 2 catalog lists:</p> |
Daniel Veillard | b8cfbd1 | 2001-10-25 10:53:28 +0000 | [diff] [blame] | 4838 | <ul> |
| 4839 | <li>the default one, global shared by all the application</li> |
Daniel Veillard | f781dba | 2006-06-09 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 Veillard | b8cfbd1 | 2001-10-25 10:53:28 +0000 | [diff] [blame] | 4844 | </ul> |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 4850 | <p>xmlInitializeCatalog(), xmlLoadCatalog() and xmlLoadCatalogs() should be |
| 4851 | used at startup to initialize the catalog, if the catalog should be |
| 4852 | initialized with specific values xmlLoadCatalog() or xmlLoadCatalogs() |
| 4853 | should be called before xmlInitializeCatalog() which would otherwise do a |
| 4854 | default initialization first.</p> |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 4861 | <p>The XML Catalog spec requires the possibility to select default |
| 4862 | preferences between public and system delegation, |
| 4863 | xmlCatalogSetDefaultPrefer() allows this, xmlCatalogSetDefaults() and |
| 4864 | xmlCatalogGetDefaults() allow to control if XML Catalogs resolution should |
| 4865 | be forbidden, allowed for global catalog, for document catalog or both, the |
| 4866 | default is to allow both.</p> |
Daniel Veillard | b8cfbd1 | 2001-10-25 10:53:28 +0000 | [diff] [blame] | 4867 | |
Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 4868 | <p>And of course xmlCatalogSetDebug() allows to generate debug messages |
| 4869 | (through the xmlGenericError() mechanism).</p> |

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

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 4886 | <p>xmlCatalogAdd() and xmlCatalogRemove() are used to dynamically modify the |

| 4889 | sure that exposing more complex interfaces (like navigation ones) would be |
| 4890 | really useful.</p> |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 4898 | <p>Since the catalog tree is built progressively, some care has been taken to |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 5168 | <p>Entities in principle are similar to simple C macros. An entity defines an |

| 5173 | beginning). Example:</p> |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 5191 | <p>One of the problems related to entities is that you may want the parser to |
| 5192 | substitute an entity's content so that you can see the replacement text in |
| 5193 | your application. Or you may prefer to keep entity references as such in the |
| 5194 | content to be able to save the document back without losing this usually |
| 5195 | precious information (if the user went through the pain of explicitly |
| 5196 | defining entities, he may have a a rather negative attitude if you blindly |
| 5197 | substitute them as saving time). The <a |
| 5198 | href="html/libxml-parser.html#xmlSubstituteEntitiesDefault">xmlSubstituteEntitiesDefault()</a> |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 5224 | <p>So, entities or no entities? Basically, it depends on your use case. I |
| 5225 | suggest that you keep the non-substituting default behaviour and avoid using |
| 5226 | entities in your XML document or data if you are not willing to handle the |
| 5227 | entity references elements in the DOM tree.</p> |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 5229 | <p>Note that at save time libxml2 enforces the conversion of the predefined |
| 5230 | entities where necessary to prevent well-formedness problems, and will also |
| 5231 | transparently replace those with chars (i.e. it will not generate entity |
| 5232 | reference elements in the DOM tree or call the reference() SAX callback when |
| 5233 | finding them in the input).</p> |

| 5236 | on top of the libxml2 SAX interface is difficult!!! If you plan to use |

| 5246 | recognizing namespace constructs in the input, and does namespace lookup |
| 5247 | automatically when building the DOM tree. A namespace declaration is |
| 5248 | associated with an in-memory structure and all elements or attributes within |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 5252 | <p>I suggest that people using libxml2 use a namespace, and declare it in the |
| 5253 | root element of their document as the default namespace. Then they don't need |
| 5254 | to use the prefix in the content but we will have a basis for future semantic |
| 5255 | refinement and merging of data from different sources. This doesn't increase |
| 5256 | the size of the XML output significantly, but significantly increases its |
| 5257 | value in the long-term. Example:</p> |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 5263 | <p>The namespace value has to be an absolute URL, but the URL doesn't have to |
| 5264 | point to any existing resource on the Web. It will bind all the element and |
| 5265 | attributes with that URL. I suggest to use an URL within a domain you |
| 5266 | control, and that the URL should contain some kind of version information if |
| 5267 | possible. For example, <code>"http://www.gnome.org/gnumeric/1.0/"</code> is a |
| 5268 | good namespace scheme.</p> |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 5270 | <p>Then when you load a file, make sure that a namespace carrying the |
| 5271 | version-independent prefix is installed on the root element of your document, |
| 5272 | and if the version information don't match something you know, warn the user |
| 5273 | and be liberal in what you accept as the input. Also do *not* try to base |
| 5274 | namespace checking on the prefix value. <foo:text> may be exactly the |
| 5275 | same as <bar:text> in another document. What really matters is the URI |
| 5276 | associated with the element or the attribute, not the prefix string (which is |
| 5277 | just 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 |
| 5279 | prefix and its URI.</p> |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 5289 | <p>Usually people object to using namespaces together with validity checking. |
| 5290 | I will try to make sure that using namespaces won't break validity checking, |
| 5291 | so even if you plan to use or currently are using validation I strongly |
| 5292 | suggest adding namespaces to your document. A default namespace scheme |
| 5293 | <code>xmlns="http://...."</code> should not break validity even on less |
| 5294 | flexible parsers. Using namespaces to mix and differentiate content coming |
| 5295 | from multiple DTDs will certainly break current validation schemes. To check |
| 5296 | such documents one needs to use schema-validation, which is supported in |

Daniel Veillard | f781dba | 2006-06-09 13:34:49 +0000 | [diff] [blame] | 5307 | <li>a general cleanup. A number of mistakes inherited from the very early |
| 5308 | versions couldn't be changed due to compatibility constraints. Example |
| 5309 | the "childs" element in the nodes.</li> |
| 5310 | <li>Uniformization of the various nodes, at least for their header and link |
| 5311 | parts (doc, parent, children, prev, next), the goal is a simpler |
| 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 |

| 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 |

| 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 |

| 5395 | <li>install the libxml-1.8.8 (and libxml-devel-1.8.8) packages</li> |

| 5406 | as the Include and Linking parameters needed to use libxml.</li> |
| 5407 | <li>install libxml2-2.3.x and libxml2-devel-2.3.x (libxml-1.8.y and |
| 5408 | libxml-devel-1.8.y can be kept simultaneously)</li> |
| 5409 | <li>remove your config.cache, relaunch your configuration mechanism, and |
| 5410 | recompile, if steps 2 and 3 were done right it should compile as-is</li> |
| 5411 | <li>Test that your application is still running correctly, if not this may |
| 5412 | be due to extra empty nodes due to formating spaces being kept in libxml2 |
| 5413 | contrary to libxml1, in that case insert xmlKeepBlanksDefault(1) in your |

Daniel Veillard | 14fff06 | 1999-06-22 21:49:07 +0000 | [diff] [blame] | 5588 | <ul> |
Daniel Veillard | f781dba | 2006-06-09 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->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> |
