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