+124907 HTML parse buffer problem when parsing larse in-memory docs
+124110 DTD validation && wrong namespace
+123564 xmllint --html --format
+
+ TODO for the XML parser and stuff:
+ ==================================
+
+ $Id$
+
+ this tend to be outdated :-\ ...
+
+DOCS:
+=====
+
+- use case of using XInclude to load for example a description.
+ order document + product base -(XSLT)-> quote with XIncludes
+ |
+ HTML output with description of parts <---(XSLT)--
+
+TODO:
+=====
+- 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/.
+- xml:id normalized value
+
+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&#xA;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).
+
