Annotation of XML/TODO, revision 1.27
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.
1.18 daniel 17:
18: TODO:
19: =====
20:
1.24 daniel 21: - Get OASIS testsuite to a more friendly result, check all the results
22: once stable.
23: http://xmlsoft.org/conf/result.html
24:
25: - Optimization of tag strings allocation.
26:
27: - maintain coherency of namespace when doing cut'n paste operations
28: => the functions are coded, but need testing
29:
30: - function to rebuild the ID table ?
31:
32: - Parsing of a well balanced chunk
33:
34: - dynamically adapt the alloc entry point to use g_alloc()/g_free()
35: if the programmer wants it
36:
37: - Validity checking problems for ENTITY ENTITIES attributes
38:
39: - Validity checking problems for NOTATIONS attributes
40:
41: - Check attribute normalization especially xmlGetProp()
42:
43: EXTENSIONS:
44: ===========
1.26 daniel 45: - URI module: validation, base, etc ...
1.21 daniel 46: - Tools to produce man pages from the SGML docs.
1.16 daniel 47: - Finish XPath
1.18 daniel 48: => attributes addressing troubles
1.19 daniel 49: => defaulted attributes handling
50: => namespace axis ?
1.16 daniel 51:
52: - Add Xpointer recognition/API
53:
54: - Add Xlink recognition/API
1.18 daniel 55: => started adding an xlink.[ch] with a unified API for XML and HTML.
1.16 daniel 56:
57: - Implement XSLT
1.19 daniel 58: => seems that someone volunteered ?!?
1.16 daniel 59:
1.18 daniel 60: - Implement XSchemas
61:
1.16 daniel 62: - O2K parsing;
63: => this is a somewhat ugly mix of HTML and XML, adding a specific
64: routine in the comment parsing code of HTML and plug the XML
65: parsing one in-there should not be too hard. Key point is to get
66: XSL to transform all this to something decent ...
67:
1.18 daniel 68: - extend the shell with:
69: - edit
70: - load/save
71: - mv (yum, yum, but it's harder because directories are ordered in
72: our case, mvup and mvdown would be required)
1.16 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:
1.24 daniel 86:
87: Done:
88: =====
89:
1.27 ! daniel 90: - Save Dtds using the children list instead of dumping the tables,
! 91: order is preserved as well as comments and PIs
! 92: - Wrote a notice of changes requires to go from 1.x to 2.x
! 93: - make sure that all SAX callbacks are disabled if a WF error is detected
! 94: - checking/handling of newline normalization
! 95: http://localhost/www.xml.com/axml/target.html#sec-line-ends
1.25 daniel 96: - correct checking of '&' '%' on entities content.
97: - checking of PE/Nesting on entities declaration
98: - checking/handling of xml:space
99: - checking done.
100: - handling done, not well tested
1.24 daniel 101: - Language identification code, productions [33] to [38]
102: => done, the check has been added and report WFness errors
103: - Conditional sections in DTDs [61] to [65]
104: => should this crap be really implemented ???
105: => Yep OASIS testsuite uses them
106: - Allow parsed entities defined in the internal subset to override
107: the ones defined in the external subset (DtD customization).
108: => This mean that the entity content should be computed only at
109: use time, i.e. keep the orig string only at parse time and expand
110: only when referenced from the external subset :-(
111: Needed for complete use of most DTD from Eve Maler
112: - Add regression tests for all WFC errors
113: => did some in test/WFC
114: => added OASIS testsuite routines
115: http://xmlsoft.org/conf/result.html
1.22 daniel 116:
1.23 daniel 117: - I18N: http://wap.trondheim.com/vaer/index.phtml is not XML and accepted
118: by the XML parser, UTF-8 should be checked when there is no "encoding"
119: declared !
1.24 daniel 120: - Support for UTF-8 and UTF-16 encoding
121: => added some convertion routines provided by Martin Durst
122: patched them, got fixes from @@@
123: I plan to keep everything internally as UTF-8 (or ISO-Latin-X)
124: this is slightly more costly but more compact, and recent processors
125: efficiency is cache related. The key for good performances is keeping
126: the data set small, so will I.
127: => the new progressive reading routines call the detection code
128: is enabled, tested the ISO->UTF-8 stuff
1.20 daniel 129: - External entities loading:
130: - allow override by client code
131: - make sure it is alled for all external entities referenced
132: Done, client code should use xmlSetExternalEntityLoader() to set
133: the default loading routine. It will be called each time an external
134: entity entity resolution is triggered.
135: - maintain ID coherency when removing/changing attributes
136: The function used to deallocate attributes now check for it being an
137: ID and removes it from the table.
138: - push mode parsing i.e. non-blocking state based parser
139: done, both for XML and HTML parsers. Use xmlCreatePushParserCtxt()
140: and xmlParseChunk() and html counterparts.
141: The tester program now has a --push option to select that parser
142: front-end. Douplicated tests to use both and check results are similar.
143:
1.18 daniel 144: - Most of XPath, still see some troubles and occasionnal memleaks.
145: - an XML shell, allowing to traverse/manipulate an XML document with
146: a shell like interface, and using XPath for the anming syntax
1.20 daniel 147: - use of readline and history added when available
148: - the shell interface has been cleanly separated and moved to debugXML.c
1.18 daniel 149: - HTML parser, should be fairly stable now
150: - API to search the lang of an attribute
151: - Collect IDs at parsing and maintain a table.
152: PBM: maintain the table coherency
153: PBM: how to detect ID types in absence of DtD !
154: - Use it for XPath ID support
155: - Add validity checking
156: Should be finished now !
1.16 daniel 157: - Add regression tests with entity substitutions
158:
159: - External Parsed entities, either XML or external Subset [78] and [79]
160: parsing the xmllang DtD now works, so it should be sufficient for
161: most cases !
162:
163: - progressive reading. The entity support is a first step toward
1.7 daniel 164: asbtraction of an input stream. A large part of the context is still
165: located on the stack, moving to a state machine and putting everyting
166: in the parsing context should provide an adequate solution.
1.8 daniel 167: => Rather than progressive parsing, give more power to the SAX-like
168: interface. Currently the DOM-like representation is built but
1.18 daniel 169: => it should be possible to define that only as a set of SAX callbacks
170: and remove the tree creation from the parser code.
171: DONE
1.8 daniel 172:
1.1 daniel 173: - DOM support, instead of using a proprietary in memory
174: format for the document representation, the parser should
175: call a DOM API to actually build the resulting document.
176: Then the parser becomes independent of the in-memory
177: representation of the document. Even better using RPC's
178: the parser can actually build the document in another
179: program.
1.8 daniel 180: => Work started, now the internal representation is by default
181: very near a direct DOM implementation. The DOM glue is implemented
1.16 daniel 182: as a separate module. See the GNOME gdome module.
183:
1.2 daniel 184: - C++ support : John Ehresman <jehresma@dsg.harvard.edu>
1.6 daniel 185: - Updated code to follow more recent specs, added compatibility flag
1.7 daniel 186: - Better error handling, use a dedicated, overridable error
187: handling function.
188: - Support for CDATA.
189: - Keep track of line numbers for better error reporting.
190: - Support for PI (SAX one).
1.8 daniel 191: - Support for Comments (bad, should be in ASAP, they are parsed
192: but not stored), should be configurable.
193: - Improve the support of entities on save (+SAX).
