1.1 daniel 1:
1.16 daniel 2: TODO for the XML parser and stuff:
3: ==================================
4:
1.24 daniel 5: TODO:
6: =====
7:
1.25 ! daniel 8: - extend validity checks to go through entities content instead of
! 9: just labelling them PCDATA
! 10: - add support for the trick from Henry conf/sun/valid/empty.xml
! 11: - checking/handling of newline normalization
! 12: http://localhost/www.xml.com/axml/target.html#sec-line-ends
! 13: - Correct standalone checking/emitting (hard)
! 14: 2.9 Standalone Document Declaration
1.18 daniel 15:
16: TODO:
17: =====
18:
1.24 daniel 19: - Get OASIS testsuite to a more friendly result, check all the results
20: once stable.
21: http://xmlsoft.org/conf/result.html
22:
23: - Optimization of tag strings allocation.
24:
25: - maintain coherency of namespace when doing cut'n paste operations
26: => the functions are coded, but need testing
27:
28: - function to rebuild the ID table ?
29:
30: - Parsing of a well balanced chunk
31:
32: - dynamically adapt the alloc entry point to use g_alloc()/g_free()
33: if the programmer wants it
34:
35: - Validity checking problems for ENTITY ENTITIES attributes
36:
37: - Validity checking problems for NOTATIONS attributes
38:
39: - Check attribute normalization especially xmlGetProp()
40:
41: EXTENSIONS:
42: ===========
1.21 daniel 43: - Tools to produce man pages from the SGML docs.
1.17 daniel 44:
1.16 daniel 45: - Finish XPath
1.18 daniel 46: => attributes addressing troubles
1.19 daniel 47: => defaulted attributes handling
48: => namespace axis ?
1.16 daniel 49:
50: - Add Xpointer recognition/API
51:
52: - Add Xlink recognition/API
1.18 daniel 53: => started adding an xlink.[ch] with a unified API for XML and HTML.
1.16 daniel 54:
55: - Implement XSLT
1.19 daniel 56: => seems that someone volunteered ?!?
1.16 daniel 57:
1.18 daniel 58: - Implement XSchemas
59:
1.16 daniel 60: - O2K parsing;
61: => this is a somewhat ugly mix of HTML and XML, adding a specific
62: routine in the comment parsing code of HTML and plug the XML
63: parsing one in-there should not be too hard. Key point is to get
64: XSL to transform all this to something decent ...
65:
1.18 daniel 66: - extend the shell with:
67: - edit
68: - load/save
69: - mv (yum, yum, but it's harder because directories are ordered in
70: our case, mvup and mvdown would be required)
1.16 daniel 71:
1.20 daniel 72: - Add HTML validation using the XHTML DTD
73: - problem: do we want to keep and maintain the code for handling
74: DTD/System ID cache directly in libxml ?
75:
76: - Add a DTD cache prefilled with xhtml DTDs and entities and a program to
77: manage them -> like the /usr/bin/install-catalog from SGML
78: right place seems $datadir/xmldtds
79:
80: - turn tester into a generic program xml-test installed with xml-devel
1.16 daniel 81:
1.19 daniel 82: - Add output to XHTML in case of HTML documents.
83:
1.24 daniel 84:
85: Done:
86: =====
87:
1.25 ! daniel 88: - correct checking of '&' '%' on entities content.
! 89: - checking of PE/Nesting on entities declaration
! 90: - checking/handling of xml:space
! 91: - checking done.
! 92: - handling done, not well tested
1.24 daniel 93: - Language identification code, productions [33] to [38]
94: => done, the check has been added and report WFness errors
95: - Conditional sections in DTDs [61] to [65]
96: => should this crap be really implemented ???
97: => Yep OASIS testsuite uses them
98: - Allow parsed entities defined in the internal subset to override
99: the ones defined in the external subset (DtD customization).
100: => This mean that the entity content should be computed only at
101: use time, i.e. keep the orig string only at parse time and expand
102: only when referenced from the external subset :-(
103: Needed for complete use of most DTD from Eve Maler
104: - Add regression tests for all WFC errors
105: => did some in test/WFC
106: => added OASIS testsuite routines
107: http://xmlsoft.org/conf/result.html
1.22 daniel 108:
1.23 daniel 109: - I18N: http://wap.trondheim.com/vaer/index.phtml is not XML and accepted
110: by the XML parser, UTF-8 should be checked when there is no "encoding"
111: declared !
1.24 daniel 112: - Support for UTF-8 and UTF-16 encoding
113: => added some convertion routines provided by Martin Durst
114: patched them, got fixes from @@@
115: I plan to keep everything internally as UTF-8 (or ISO-Latin-X)
116: this is slightly more costly but more compact, and recent processors
117: efficiency is cache related. The key for good performances is keeping
118: the data set small, so will I.
119: => the new progressive reading routines call the detection code
120: is enabled, tested the ISO->UTF-8 stuff
1.20 daniel 121: - External entities loading:
122: - allow override by client code
123: - make sure it is alled for all external entities referenced
124: Done, client code should use xmlSetExternalEntityLoader() to set
125: the default loading routine. It will be called each time an external
126: entity entity resolution is triggered.
127: - maintain ID coherency when removing/changing attributes
128: The function used to deallocate attributes now check for it being an
129: ID and removes it from the table.
130: - push mode parsing i.e. non-blocking state based parser
131: done, both for XML and HTML parsers. Use xmlCreatePushParserCtxt()
132: and xmlParseChunk() and html counterparts.
133: The tester program now has a --push option to select that parser
134: front-end. Douplicated tests to use both and check results are similar.
135:
1.18 daniel 136: - Most of XPath, still see some troubles and occasionnal memleaks.
137: - an XML shell, allowing to traverse/manipulate an XML document with
138: a shell like interface, and using XPath for the anming syntax
1.20 daniel 139: - use of readline and history added when available
140: - the shell interface has been cleanly separated and moved to debugXML.c
1.18 daniel 141: - HTML parser, should be fairly stable now
142: - API to search the lang of an attribute
143: - Collect IDs at parsing and maintain a table.
144: PBM: maintain the table coherency
145: PBM: how to detect ID types in absence of DtD !
146: - Use it for XPath ID support
147: - Add validity checking
148: Should be finished now !
1.16 daniel 149: - Add regression tests with entity substitutions
150:
151: - External Parsed entities, either XML or external Subset [78] and [79]
152: parsing the xmllang DtD now works, so it should be sufficient for
153: most cases !
154:
155: - progressive reading. The entity support is a first step toward
1.7 daniel 156: asbtraction of an input stream. A large part of the context is still
157: located on the stack, moving to a state machine and putting everyting
158: in the parsing context should provide an adequate solution.
1.8 daniel 159: => Rather than progressive parsing, give more power to the SAX-like
160: interface. Currently the DOM-like representation is built but
1.18 daniel 161: => it should be possible to define that only as a set of SAX callbacks
162: and remove the tree creation from the parser code.
163: DONE
1.8 daniel 164:
1.1 daniel 165: - DOM support, instead of using a proprietary in memory
166: format for the document representation, the parser should
167: call a DOM API to actually build the resulting document.
168: Then the parser becomes independent of the in-memory
169: representation of the document. Even better using RPC's
170: the parser can actually build the document in another
171: program.
1.8 daniel 172: => Work started, now the internal representation is by default
173: very near a direct DOM implementation. The DOM glue is implemented
1.16 daniel 174: as a separate module. See the GNOME gdome module.
175:
1.2 daniel 176: - C++ support : John Ehresman <jehresma@dsg.harvard.edu>
1.6 daniel 177: - Updated code to follow more recent specs, added compatibility flag
1.7 daniel 178: - Better error handling, use a dedicated, overridable error
179: handling function.
180: - Support for CDATA.
181: - Keep track of line numbers for better error reporting.
182: - Support for PI (SAX one).
1.8 daniel 183: - Support for Comments (bad, should be in ASAP, they are parsed
184: but not stored), should be configurable.
185: - Improve the support of entities on save (+SAX).
