1.1 daniel 1:
1.16 daniel 2: TODO for the XML parser and stuff:
3: ==================================
4:
1.24 ! daniel 5: TODO:
! 6: =====
! 7:
! 8: - checking of PE/Nesting on entities declaration
1.18 daniel 9:
10: TODO:
11: =====
12:
1.24 ! daniel 13: - Get OASIS testsuite to a more friendly result, check all the results
! 14: once stable.
! 15: http://xmlsoft.org/conf/result.html
! 16:
! 17: - Optimization of tag strings allocation.
! 18:
! 19: - maintain coherency of namespace when doing cut'n paste operations
! 20: => the functions are coded, but need testing
! 21:
! 22: - function to rebuild the ID table ?
! 23:
! 24: - Parsing of a well balanced chunk
! 25:
! 26: - dynamically adapt the alloc entry point to use g_alloc()/g_free()
! 27: if the programmer wants it
! 28:
! 29: - Validity checking problems for ENTITY ENTITIES attributes
! 30:
! 31: - Validity checking problems for NOTATIONS attributes
! 32:
! 33: - Check attribute normalization especially xmlGetProp()
! 34:
! 35: EXTENSIONS:
! 36: ===========
1.21 daniel 37: - Tools to produce man pages from the SGML docs.
1.17 daniel 38:
1.16 daniel 39: - Finish XPath
1.18 daniel 40: => attributes addressing troubles
1.19 daniel 41: => defaulted attributes handling
42: => namespace axis ?
1.16 daniel 43:
44: - Add Xpointer recognition/API
45:
46: - Add Xlink recognition/API
1.18 daniel 47: => started adding an xlink.[ch] with a unified API for XML and HTML.
1.16 daniel 48:
49: - Implement XSLT
1.19 daniel 50: => seems that someone volunteered ?!?
1.16 daniel 51:
1.18 daniel 52: - Implement XSchemas
53:
1.16 daniel 54: - O2K parsing;
55: => this is a somewhat ugly mix of HTML and XML, adding a specific
56: routine in the comment parsing code of HTML and plug the XML
57: parsing one in-there should not be too hard. Key point is to get
58: XSL to transform all this to something decent ...
59:
1.18 daniel 60: - extend the shell with:
61: - edit
62: - load/save
63: - mv (yum, yum, but it's harder because directories are ordered in
64: our case, mvup and mvdown would be required)
1.16 daniel 65:
1.20 daniel 66: - Add HTML validation using the XHTML DTD
67: - problem: do we want to keep and maintain the code for handling
68: DTD/System ID cache directly in libxml ?
69:
70: - Add a DTD cache prefilled with xhtml DTDs and entities and a program to
71: manage them -> like the /usr/bin/install-catalog from SGML
72: right place seems $datadir/xmldtds
73:
74: - turn tester into a generic program xml-test installed with xml-devel
1.16 daniel 75:
1.19 daniel 76: - Add output to XHTML in case of HTML documents.
77:
1.24 ! daniel 78:
! 79: Done:
! 80: =====
! 81:
! 82: - Language identification code, productions [33] to [38]
! 83: => done, the check has been added and report WFness errors
! 84: - Conditional sections in DTDs [61] to [65]
! 85: => should this crap be really implemented ???
! 86: => Yep OASIS testsuite uses them
! 87: - Allow parsed entities defined in the internal subset to override
! 88: the ones defined in the external subset (DtD customization).
! 89: => This mean that the entity content should be computed only at
! 90: use time, i.e. keep the orig string only at parse time and expand
! 91: only when referenced from the external subset :-(
! 92: Needed for complete use of most DTD from Eve Maler
! 93: - Add regression tests for all WFC errors
! 94: => did some in test/WFC
! 95: => added OASIS testsuite routines
! 96: http://xmlsoft.org/conf/result.html
1.22 daniel 97:
1.23 daniel 98: - I18N: http://wap.trondheim.com/vaer/index.phtml is not XML and accepted
99: by the XML parser, UTF-8 should be checked when there is no "encoding"
100: declared !
1.24 ! daniel 101: - Support for UTF-8 and UTF-16 encoding
! 102: => added some convertion routines provided by Martin Durst
! 103: patched them, got fixes from @@@
! 104: I plan to keep everything internally as UTF-8 (or ISO-Latin-X)
! 105: this is slightly more costly but more compact, and recent processors
! 106: efficiency is cache related. The key for good performances is keeping
! 107: the data set small, so will I.
! 108: => the new progressive reading routines call the detection code
! 109: is enabled, tested the ISO->UTF-8 stuff
1.20 daniel 110: - External entities loading:
111: - allow override by client code
112: - make sure it is alled for all external entities referenced
113: Done, client code should use xmlSetExternalEntityLoader() to set
114: the default loading routine. It will be called each time an external
115: entity entity resolution is triggered.
116: - maintain ID coherency when removing/changing attributes
117: The function used to deallocate attributes now check for it being an
118: ID and removes it from the table.
119: - push mode parsing i.e. non-blocking state based parser
120: done, both for XML and HTML parsers. Use xmlCreatePushParserCtxt()
121: and xmlParseChunk() and html counterparts.
122: The tester program now has a --push option to select that parser
123: front-end. Douplicated tests to use both and check results are similar.
124:
1.18 daniel 125: - Most of XPath, still see some troubles and occasionnal memleaks.
126: - an XML shell, allowing to traverse/manipulate an XML document with
127: a shell like interface, and using XPath for the anming syntax
1.20 daniel 128: - use of readline and history added when available
129: - the shell interface has been cleanly separated and moved to debugXML.c
1.18 daniel 130: - HTML parser, should be fairly stable now
131: - API to search the lang of an attribute
132: - Collect IDs at parsing and maintain a table.
133: PBM: maintain the table coherency
134: PBM: how to detect ID types in absence of DtD !
135: - Use it for XPath ID support
136: - Add validity checking
137: Should be finished now !
1.16 daniel 138: - Add regression tests with entity substitutions
139:
140: - External Parsed entities, either XML or external Subset [78] and [79]
141: parsing the xmllang DtD now works, so it should be sufficient for
142: most cases !
143:
144: - progressive reading. The entity support is a first step toward
1.7 daniel 145: asbtraction of an input stream. A large part of the context is still
146: located on the stack, moving to a state machine and putting everyting
147: in the parsing context should provide an adequate solution.
1.8 daniel 148: => Rather than progressive parsing, give more power to the SAX-like
149: interface. Currently the DOM-like representation is built but
1.18 daniel 150: => it should be possible to define that only as a set of SAX callbacks
151: and remove the tree creation from the parser code.
152: DONE
1.8 daniel 153:
1.1 daniel 154: - DOM support, instead of using a proprietary in memory
155: format for the document representation, the parser should
156: call a DOM API to actually build the resulting document.
157: Then the parser becomes independent of the in-memory
158: representation of the document. Even better using RPC's
159: the parser can actually build the document in another
160: program.
1.8 daniel 161: => Work started, now the internal representation is by default
162: very near a direct DOM implementation. The DOM glue is implemented
1.16 daniel 163: as a separate module. See the GNOME gdome module.
164:
1.2 daniel 165: - C++ support : John Ehresman <jehresma@dsg.harvard.edu>
1.6 daniel 166: - Updated code to follow more recent specs, added compatibility flag
1.7 daniel 167: - Better error handling, use a dedicated, overridable error
168: handling function.
169: - Support for CDATA.
170: - Keep track of line numbers for better error reporting.
171: - Support for PI (SAX one).
1.8 daniel 172: - Support for Comments (bad, should be in ASAP, they are parsed
173: but not stored), should be configurable.
174: - Improve the support of entities on save (+SAX).
