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:
1.29 ! daniel 27: - Optimization of tag strings allocation ?
1.24 daniel 28:
29: - maintain coherency of namespace when doing cut'n paste operations
30: => the functions are coded, but need testing
31:
1.29 ! daniel 32: - function to rebuild the ID table
! 33: - functions to rebuild the DTD hash tables (after DTD changes).
1.24 daniel 34:

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