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: - Correct standalone checking/emitting (hard)
12: 2.9 Standalone Document Declaration
1.27 daniel 13: - URI checkings (no fragments) rfc2396.txt
14: - Better checking of external parsed entities TAG 1234
15: - Find way of representing PERefs in the Dtd so that %entity; can
16: be saved back.
1.28 ! daniel 17: - Go through erratas and do the cleanup.

1.18 daniel 19:
20: TODO:
21: =====
22:
1.24 daniel 23: - Get OASIS testsuite to a more friendly result, check all the results
24: once stable.
25: http://xmlsoft.org/conf/result.html
26:
27: - Optimization of tag strings allocation.
28:
29: - maintain coherency of namespace when doing cut'n paste operations
30: => the functions are coded, but need testing
31:
32: - function to rebuild the ID table ?
33:
34: - Parsing of a well balanced chunk
35:
36: - dynamically adapt the alloc entry point to use g_alloc()/g_free()
37: if the programmer wants it
38:
39: - Validity checking problems for ENTITY ENTITIES attributes
40:
41: - Validity checking problems for NOTATIONS attributes
42:
43: - Check attribute normalization especially xmlGetProp()
44:
45: EXTENSIONS:
46: ===========
1.26 daniel 47: - URI module: validation, base, etc ...
1.21 daniel 48: - Tools to produce man pages from the SGML docs.
1.16 daniel 49: - Finish XPath
1.18 daniel 50: => attributes addressing troubles
1.19 daniel 51: => defaulted attributes handling
52: => namespace axis ?
1.16 daniel 53:
54: - Add Xpointer recognition/API
55:
56: - Add Xlink recognition/API
1.18 daniel 57: => started adding an xlink.[ch] with a unified API for XML and HTML.
1.16 daniel 58:
59: - Implement XSLT
1.19 daniel 60: => seems that someone volunteered ?!?
1.16 daniel 61:
1.18 daniel 62: - Implement XSchemas
63:
1.16 daniel 64: - O2K parsing;
65: => this is a somewhat ugly mix of HTML and XML, adding a specific
66: routine in the comment parsing code of HTML and plug the XML
67: parsing one in-there should not be too hard. Key point is to get
68: XSL to transform all this to something decent ...
69:
1.18 daniel 70: - extend the shell with:
71: - edit
72: - load/save
73: - mv (yum, yum, but it's harder because directories are ordered in
74: our case, mvup and mvdown would be required)
1.16 daniel 75:
1.20 daniel 76: - Add HTML validation using the XHTML DTD
77: - problem: do we want to keep and maintain the code for handling
78: DTD/System ID cache directly in libxml ?
79:
80: - Add a DTD cache prefilled with xhtml DTDs and entities and a program to
81: manage them -> like the /usr/bin/install-catalog from SGML
82: right place seems $datadir/xmldtds
83:
84: - turn tester into a generic program xml-test installed with xml-devel
1.16 daniel 85:
1.19 daniel 86: - Add output to XHTML in case of HTML documents.
87:
1.24 daniel 88:
89: Done:
90: =====
91:
1.27 daniel 92: - Save Dtds using the children list instead of dumping the tables,
93: order is preserved as well as comments and PIs
94: - Wrote a notice of changes requires to go from 1.x to 2.x
95: - make sure that all SAX callbacks are disabled if a WF error is detected
96: - checking/handling of newline normalization
97: http://localhost/www.xml.com/axml/target.html#sec-line-ends
1.25 daniel 98: - correct checking of '&' '%' on entities content.
99: - checking of PE/Nesting on entities declaration
100: - checking/handling of xml:space
101: - checking done.
102: - handling done, not well tested
1.24 daniel 103: - Language identification code, productions [33] to [38]
104: => done, the check has been added and report WFness errors
105: - Conditional sections in DTDs [61] to [65]
106: => should this crap be really implemented ???
107: => Yep OASIS testsuite uses them
108: - Allow parsed entities defined in the internal subset to override
109: the ones defined in the external subset (DtD customization).
110: => This mean that the entity content should be computed only at
111: use time, i.e. keep the orig string only at parse time and expand
112: only when referenced from the external subset :-(
113: Needed for complete use of most DTD from Eve Maler
114: - Add regression tests for all WFC errors
115: => did some in test/WFC
116: => added OASIS testsuite routines
117: http://xmlsoft.org/conf/result.html
1.22 daniel 118:
1.23 daniel 119: - I18N: http://wap.trondheim.com/vaer/index.phtml is not XML and accepted
120: by the XML parser, UTF-8 should be checked when there is no "encoding"
121: declared !
1.24 daniel 122: - Support for UTF-8 and UTF-16 encoding
123: => added some convertion routines provided by Martin Durst
124: patched them, got fixes from @@@
125: I plan to keep everything internally as UTF-8 (or ISO-Latin-X)
126: this is slightly more costly but more compact, and recent processors
127: efficiency is cache related. The key for good performances is keeping
128: the data set small, so will I.
129: => the new progressive reading routines call the detection code
130: is enabled, tested the ISO->UTF-8 stuff
1.20 daniel 131: - External entities loading:
132: - allow override by client code
133: - make sure it is alled for all external entities referenced
134: Done, client code should use xmlSetExternalEntityLoader() to set
135: the default loading routine. It will be called each time an external
136: entity entity resolution is triggered.
137: - maintain ID coherency when removing/changing attributes
138: The function used to deallocate attributes now check for it being an
139: ID and removes it from the table.
140: - push mode parsing i.e. non-blocking state based parser
141: done, both for XML and HTML parsers. Use xmlCreatePushParserCtxt()
142: and xmlParseChunk() and html counterparts.
143: The tester program now has a --push option to select that parser
144: front-end. Douplicated tests to use both and check results are similar.
145:
1.18 daniel 146: - Most of XPath, still see some troubles and occasionnal memleaks.
147: - an XML shell, allowing to traverse/manipulate an XML document with
148: a shell like interface, and using XPath for the anming syntax
1.20 daniel 149: - use of readline and history added when available
150: - the shell interface has been cleanly separated and moved to debugXML.c
1.18 daniel 151: - HTML parser, should be fairly stable now
152: - API to search the lang of an attribute
153: - Collect IDs at parsing and maintain a table.
154: PBM: maintain the table coherency
155: PBM: how to detect ID types in absence of DtD !
156: - Use it for XPath ID support
157: - Add validity checking
158: Should be finished now !
1.16 daniel 159: - Add regression tests with entity substitutions
160:
161: - External Parsed entities, either XML or external Subset [78] and [79]
162: parsing the xmllang DtD now works, so it should be sufficient for
163: most cases !
164:
165: - progressive reading. The entity support is a first step toward
1.7 daniel 166: asbtraction of an input stream. A large part of the context is still
167: located on the stack, moving to a state machine and putting everyting
168: in the parsing context should provide an adequate solution.
1.8 daniel 169: => Rather than progressive parsing, give more power to the SAX-like
170: interface. Currently the DOM-like representation is built but
1.18 daniel 171: => it should be possible to define that only as a set of SAX callbacks
172: and remove the tree creation from the parser code.
173: DONE
1.8 daniel 174:
1.1 daniel 175: - DOM support, instead of using a proprietary in memory
176: format for the document representation, the parser should
177: call a DOM API to actually build the resulting document.
178: Then the parser becomes independent of the in-memory
179: representation of the document. Even better using RPC's
180: the parser can actually build the document in another
181: program.
1.8 daniel 182: => Work started, now the internal representation is by default
183: very near a direct DOM implementation. The DOM glue is implemented
1.16 daniel 184: as a separate module. See the GNOME gdome module.
185:
1.2 daniel 186: - C++ support : John Ehresman <jehresma@dsg.harvard.edu>
1.6 daniel 187: - Updated code to follow more recent specs, added compatibility flag
1.7 daniel 188: - Better error handling, use a dedicated, overridable error
189: handling function.
190: - Support for CDATA.
191: - Keep track of line numbers for better error reporting.
192: - Support for PI (SAX one).
1.8 daniel 193: - Support for Comments (bad, should be in ASAP, they are parsed
194: but not stored), should be configurable.
195: - Improve the support of entities on save (+SAX).
