| [17:21:38] <PGrosso> DV, you have an action to Check what your parser does on E20. Have you done this? |

| [17:39:07] <DV> paphio:~/XML -> |
| [17:39:16] <DV> I think it's okay |
| [17:40:28] <PGrosso> DV, so you're saying that your parser implements E20 correctly, right? |
| [17:40:48] <DV> assuming I understood E20 point correctly, yes |
| [17:41:15] <DV> and that's because I'm unsure taht I pasted the est document and result |
| [17:41:25] <DV> s/ est/ test/ |
| [17:48:56] <richard> does your parser say that document is invalid? |
| [17:49:03] <DV> richard: did I understood it ? |
| [17:49:11] <DV> richard: no it considers it valid |
| [17:49:16] <richard> that document is invalid |
| [17:49:47] <DV> ah , well it's unclear |
| [17:50:03] <richard> the normalized value is a-tab-b, which you are correctly serializing as a	b, but it is invalid |
| [17:50:11] <DV> richard: okay |
| [17:50:23] <DV> that should be really easy to fix |
| [17:50:39] <richard> the validity check should require a single space between tokens |
| [17:51:03] <DV> no leading and no trailing either |
| [17:51:07] <richard> right |
| [17:51:18] <DV> which makes sense |
| [17:52:42] <richard> a b is valid, because it turns into a-space-b anyway without any normalization |
| [17:54:31] <DV> okay that's attr2 attr2=" a b " |
| [17:54:44] * DV tends to still think in hexa |
| [17:55:59] <DV> richard: and attr2="a  b" would lead to a validity error too then, if I understand correctly |
| [17:56:37] <richard> attr2 is valid |
| [17:57:11] <richard> the normalized value is a space b |
| - XInclude at the SAX level (libSRVG) |
| - fix the C code prototype to bring back doc/libxml-undocumented.txt |
| to a reasonable level |
| - Computation of base when HTTP redirect occurs, might affect HTTP |
| interfaces. |
| - Computation of base in XInclude. Relativization of URIs. |
| - listing all attributes in a node. |
| - Better checking of external parsed entities TAG 1234 |
| - Go through erratas and do the cleanup. |
| http://www.w3.org/XML/xml-19980210-errata ... started ... |
| - jamesh suggestion: SAX like functions to save a document ie. call a |
| function to open a new element with given attributes, write character |
| data, close last element, etc |
| + inversted SAX, initial patch in April 2002 archives. |
| - htmlParseDoc has parameter encoding which is not used. |
| Function htmlCreateDocParserCtxt ignore it. |
| - fix realloc() usage. |
| - Stricten the UTF8 conformance (Martin Duerst): |
| http://www.w3.org/2001/06/utf-8-test/. |
| The bad files are in http://www.w3.org/2001/06/utf-8-wrong/. |
| |
| |
| TODO: |
| ===== |
| |
| - move all string manipulation functions (xmlStrdup, xmlStrlen, etc.) to |
| global.c. Bjorn noted that the following files depends on parser.o solely |
| because of these string functions: entities.o, global.o, hash.o, tree.o, |
| xmlIO.o, and xpath.o. |
| |
| - Optimization of tag strings allocation ? |
| |
| - maintain coherency of namespace when doing cut'n paste operations |
| => the functions are coded, but need testing |
| |
| - function to rebuild the ID table |
| - functions to rebuild the DTD hash tables (after DTD changes). |
| |
| |
| EXTENSIONS: |
| =========== |
| |
| - Tools to produce man pages from the SGML docs. |
| |
| - Add Xpointer recognition/API |
| |
| - Add Xlink recognition/API |
| => started adding an xlink.[ch] with a unified API for XML and HTML. |
| it's crap :-( |
| |
| - Implement XSchemas |
| => Really need to be done <grin/> |
| - datatype are complete, but structure support is very limited. |
| |
| - extend the shell with: |
| - edit |
| - load/save |
| - mv (yum, yum, but it's harder because directories are ordered in |
| our case, mvup and mvdown would be required) |
| |
| |
| Done: |
| ===== |
| |
| - Add HTML validation using the XHTML DTD |
| - problem: do we want to keep and maintain the code for handling |
| DTD/System ID cache directly in libxml ? |
| => not really done that way, but there are new APIs to check elements |
| or attributes. Otherwise XHTML validation directly ... |
| |
| - XML Schemas datatypes except Base64 and BinHex |
| |
| - Relax NG validation |
| |
| - XmlTextReader streaming API + validation |
| |
| - Add a DTD cache prefilled with xhtml DTDs and entities and a program to |
| manage them -> like the /usr/bin/install-catalog from SGML |
| right place seems $datadir/xmldtds |
| Maybe this is better left to user apps |
| => use a catalog instead , and xhtml1-dtd package |
| |
| - Add output to XHTML |
| => XML serializer automatically recognize the DTd and apply the specific |
| rules. |
| |
| - Fix output of <tst val="x
y"/> |
| |
| - compliance to XML-Namespace checking, see section 6 of |
| http://www.w3.org/TR/REC-xml-names/ |
| |
| - Correct standalone checking/emitting (hard) |
| 2.9 Standalone Document Declaration |
| |
| - Implement OASIS XML Catalog support |
| http://www.oasis-open.org/committees/entity/ |
| |
| - Get OASIS testsuite to a more friendly result, check all the results |
| once stable. the check-xml-test-suite.py script does this |
| |
| - Implement XSLT |
| => libxslt |
| |
| - Finish XPath |
| => attributes addressing troubles |
| => defaulted attributes handling |
| => namespace axis ? |
| done as XSLT got debugged |
| |
| - bug reported by Michael Meallin on validation problems |
| => Actually means I need to add support (and warn) for non-deterministic |
| content model. |
| - Handle undefined namespaces in entity contents better ... at least |
| issue a warning |
| - DOM needs |
| int xmlPruneProp(xmlNodePtr node, xmlAtttrPtr attr); |
| => done it's actually xmlRemoveProp xmlUnsetProp xmlUnsetNsProp |
| |
| - HTML: handling of Script and style data elements, need special code in |
| the parser and saving functions (handling of < > " ' ...): |
| http://www.w3.org/TR/html4/types.html#type-script |
| Attributes are no problems since entities are accepted. |
| - DOM needs |
| xmlAttrPtr xmlNewDocProp(xmlDocPtr doc, const xmlChar *name, const xmlChar *value) |
| - problem when parsing hrefs with & with the HTML parser (IRC ac) |
| - If the internal encoding is not UTF8 saving to a given encoding doesn't |
| work => fix to force UTF8 encoding ... |
| done, added documentation too |
| - Add an ASCII I/O encoder (asciiToUTF8 and UTF8Toascii) |
| - Issue warning when using non-absolute namespaces URI. |
| - the html parser should add <head> and <body> if they don't exist |
| started, not finished. |
| Done, the automatic closing is added and 3 testcases were inserted |
| - Command to force the parser to stop parsing and ignore the rest of the file. |
| xmlStopParser() should allow this, mostly untested |
| - support for HTML empty attributes like <hr noshade> |
| - plugged iconv() in for support of a large set of encodings. |
| - xmlSwitchToEncoding() rewrite done |
| - URI checkings (no fragments) rfc2396.txt |
| - Added a clean mechanism for overload or added input methods: |
| xmlRegisterInputCallbacks() |
| - dynamically adapt the alloc entry point to use g_alloc()/g_free() |
| if the programmer wants it: |
| - use xmlMemSetup() to reset the routines used. |
| - Check attribute normalization especially xmlGetProp() |
| - Validity checking problems for NOTATIONS attributes |
| - Validity checking problems for ENTITY ENTITIES attributes |
| - Parsing of a well balanced chunk xmlParseBalancedChunkMemory() |
| - URI module: validation, base, etc ... see uri.[ch] |
| - turn tester into a generic program xmllint installed with libxml |
| - extend validity checks to go through entities content instead of |
| just labelling them PCDATA |
| - Save Dtds using the children list instead of dumping the tables, |
| order is preserved as well as comments and PIs |
| - Wrote a notice of changes requires to go from 1.x to 2.x |
| - make sure that all SAX callbacks are disabled if a WF error is detected |
| - checking/handling of newline normalization |
| http://localhost/www.xml.com/axml/target.html#sec-line-ends |
| - correct checking of '&' '%' on entities content. |
| - checking of PE/Nesting on entities declaration |
| - checking/handling of xml:space |
| - checking done. |
| - handling done, not well tested |
| - Language identification code, productions [33] to [38] |
| => done, the check has been added and report WFness errors |
| - Conditional sections in DTDs [61] to [65] |
| => should this crap be really implemented ??? |
| => Yep OASIS testsuite uses them |
| - Allow parsed entities defined in the internal subset to override |
| the ones defined in the external subset (DtD customization). |
| => This mean that the entity content should be computed only at |
| use time, i.e. keep the orig string only at parse time and expand |
| only when referenced from the external subset :-( |
| Needed for complete use of most DTD from Eve Maler |
| - Add regression tests for all WFC errors |
| => did some in test/WFC |
| => added OASIS testsuite routines |
| http://xmlsoft.org/conf/result.html |
| |
| - I18N: http://wap.trondheim.com/vaer/index.phtml is not XML and accepted |
| by the XML parser, UTF-8 should be checked when there is no "encoding" |
| declared ! |
| - Support for UTF-8 and UTF-16 encoding |
| => added some convertion routines provided by Martin Durst |
| patched them, got fixes from @@@ |
| I plan to keep everything internally as UTF-8 (or ISO-Latin-X) |
| this is slightly more costly but more compact, and recent processors |
| efficiency is cache related. The key for good performances is keeping |
| the data set small, so will I. |
| => the new progressive reading routines call the detection code |
| is enabled, tested the ISO->UTF-8 stuff |
| - External entities loading: |
| - allow override by client code |
| - make sure it is alled for all external entities referenced |
| Done, client code should use xmlSetExternalEntityLoader() to set |
| the default loading routine. It will be called each time an external |
| entity entity resolution is triggered. |
| - maintain ID coherency when removing/changing attributes |
| The function used to deallocate attributes now check for it being an |
| ID and removes it from the table. |
| - push mode parsing i.e. non-blocking state based parser |
| done, both for XML and HTML parsers. Use xmlCreatePushParserCtxt() |
| and xmlParseChunk() and html counterparts. |
| The tester program now has a --push option to select that parser |
| front-end. Douplicated tests to use both and check results are similar. |
| |
| - Most of XPath, still see some troubles and occasionnal memleaks. |
| - an XML shell, allowing to traverse/manipulate an XML document with |
| a shell like interface, and using XPath for the anming syntax |
| - use of readline and history added when available |
| - the shell interface has been cleanly separated and moved to debugXML.c |
| - HTML parser, should be fairly stable now |
| - API to search the lang of an attribute |
| - Collect IDs at parsing and maintain a table. |
| PBM: maintain the table coherency |
| PBM: how to detect ID types in absence of DtD ! |
| - Use it for XPath ID support |
| - Add validity checking |
| Should be finished now ! |
| - Add regression tests with entity substitutions |
| |
| - External Parsed entities, either XML or external Subset [78] and [79] |
| parsing the xmllang DtD now works, so it should be sufficient for |
| most cases ! |
| |
| - progressive reading. The entity support is a first step toward |
| asbtraction of an input stream. A large part of the context is still |
| located on the stack, moving to a state machine and putting everyting |
| in the parsing context should provide an adequate solution. |
| => Rather than progressive parsing, give more power to the SAX-like |
| interface. Currently the DOM-like representation is built but |
| => it should be possible to define that only as a set of SAX callbacks |
| and remove the tree creation from the parser code. |
| DONE |
| |
| - DOM support, instead of using a proprietary in memory |
| format for the document representation, the parser should |
| call a DOM API to actually build the resulting document. |
| Then the parser becomes independent of the in-memory |
| representation of the document. Even better using RPC's |
| the parser can actually build the document in another |
| program. |
| => Work started, now the internal representation is by default |
| very near a direct DOM implementation. The DOM glue is implemented |
| as a separate module. See the GNOME gdome module. |
| |
| - C++ support : John Ehresman <jehresma@dsg.harvard.edu> |
| - Updated code to follow more recent specs, added compatibility flag |
| - Better error handling, use a dedicated, overridable error |
| handling function. |
| - Support for CDATA. |
| - Keep track of line numbers for better error reporting. |
| - Support for PI (SAX one). |
| - Support for Comments (bad, should be in ASAP, they are parsed |
| but not stored), should be configurable. |
| - Improve the support of entities on save (+SAX). |
