Daniel Veillard75c29212000-03-14 18:33:47 +0000[diff] [blame]54- Tools to produce man pages from the SGML docs.
Daniel Veillardad8f99d2000-01-15 14:20:03 +0000[diff] [blame]55- Finish XPath
56 => attributes addressing troubles
57 => defaulted attributes handling
58 => namespace axis ?
59
60- Add Xpointer recognition/API
61
62- Add Xlink recognition/API
63 => started adding an xlink.[ch] with a unified API for XML and HTML.
Daniel Veillard496a1cf2000-05-03 14:20:55 +0000[diff] [blame]64 it's crap :-(
Daniel Veillardad8f99d2000-01-15 14:20:03 +0000[diff] [blame]65
66- Implement XSLT
67 => seems that someone volunteered ?!?
68
69- Implement XSchemas
Daniel Veillard496a1cf2000-05-03 14:20:55 +0000[diff] [blame]70 => Really need to be done <grin/>
Daniel Veillardad8f99d2000-01-15 14:20:03 +0000[diff] [blame]71
72- O2K parsing;
73 => this is a somewhat ugly mix of HTML and XML, adding a specific
74 routine in the comment parsing code of HTML and plug the XML
75 parsing one in-there should not be too hard. Key point is to get
76 XSL to transform all this to something decent ...
77
Daniel Veillardad8f99d2000-01-15 14:20:03 +0000[diff] [blame]78- extend the shell with:
79 - edit
80 - load/save
81 - mv (yum, yum, but it's harder because directories are ordered in
82 our case, mvup and mvdown would be required)
83
Daniel Veillardad8f99d2000-01-15 14:20:03 +0000[diff] [blame]84- Add HTML validation using the XHTML DTD
85 - problem: do we want to keep and maintain the code for handling
86 DTD/System ID cache directly in libxml ?
87
88- Add a DTD cache prefilled with xhtml DTDs and entities and a program to
89 manage them -> like the /usr/bin/install-catalog from SGML
90 right place seems $datadir/xmldtds
Daniel Veillard361d8452000-04-03 19:48:13 +0000[diff] [blame]91 Maybe this is better left to user apps

Daniel Veillardbe803962000-06-28 23:40:59 +0000[diff] [blame^]99- support for HTML empty attributes like <hr noshade>
100- plugged iconv() in for support of a large set of encodings.
101- xmlSwitchToEncoding() rewrite done
Daniel Veillard496a1cf2000-05-03 14:20:55 +0000[diff] [blame]102- URI checkings (no fragments) rfc2396.txt
Daniel Veillard5d211f42000-04-07 17:00:24 +0000[diff] [blame]103- Added a clean mechanism for overload or added input methods:
104 xmlRegisterInputCallbacks()
Daniel Veillard361d8452000-04-03 19:48:13 +0000[diff] [blame]105- dynamically adapt the alloc entry point to use g_alloc()/g_free()
106 if the programmer wants it:
107 - use xmlMemSetup() to reset the routines used.
108- Check attribute normalization especially xmlGetProp()
109- Validity checking problems for NOTATIONS attributes
110- Validity checking problems for ENTITY ENTITIES attributes
111- Parsing of a well balanced chunk xmlParseBalancedChunkMemory()
112- URI module: validation, base, etc ... see uri.[ch]
113- turn tester into a generic program xmllint installed with libxml
Daniel Veillardec303412000-03-24 13:41:54 +0000[diff] [blame]114- extend validity checks to go through entities content instead of
115 just labelling them PCDATA
Daniel Veillard75c29212000-03-14 18:33:47 +0000[diff] [blame]116- Save Dtds using the children list instead of dumping the tables,
117 order is preserved as well as comments and PIs
118- Wrote a notice of changes requires to go from 1.x to 2.x
119- make sure that all SAX callbacks are disabled if a WF error is detected
120- checking/handling of newline normalization
121 http://localhost/www.xml.com/axml/target.html#sec-line-ends
122- correct checking of '&' '%' on entities content.
123- checking of PE/Nesting on entities declaration
124- checking/handling of xml:space
125 - checking done.
126 - handling done, not well tested
127- Language identification code, productions [33] to [38]
128 => done, the check has been added and report WFness errors
129- Conditional sections in DTDs [61] to [65]
130 => should this crap be really implemented ???
131 => Yep OASIS testsuite uses them
132- Allow parsed entities defined in the internal subset to override
133 the ones defined in the external subset (DtD customization).
134 => This mean that the entity content should be computed only at
135 use time, i.e. keep the orig string only at parse time and expand
136 only when referenced from the external subset :-(
137 Needed for complete use of most DTD from Eve Maler
138- Add regression tests for all WFC errors
139 => did some in test/WFC
140 => added OASIS testsuite routines
141 http://xmlsoft.org/conf/result.html
142
143- I18N: http://wap.trondheim.com/vaer/index.phtml is not XML and accepted
144 by the XML parser, UTF-8 should be checked when there is no "encoding"
145 declared !
146- Support for UTF-8 and UTF-16 encoding
147 => added some convertion routines provided by Martin Durst
148 patched them, got fixes from @@@
149 I plan to keep everything internally as UTF-8 (or ISO-Latin-X)
150 this is slightly more costly but more compact, and recent processors
151 efficiency is cache related. The key for good performances is keeping
152 the data set small, so will I.
153 => the new progressive reading routines call the detection code
154 is enabled, tested the ISO->UTF-8 stuff
Daniel Veillardad8f99d2000-01-15 14:20:03 +0000[diff] [blame]155- External entities loading:
156 - allow override by client code
157 - make sure it is alled for all external entities referenced
158 Done, client code should use xmlSetExternalEntityLoader() to set
159 the default loading routine. It will be called each time an external
160 entity entity resolution is triggered.
161- maintain ID coherency when removing/changing attributes
162 The function used to deallocate attributes now check for it being an
163 ID and removes it from the table.
164- push mode parsing i.e. non-blocking state based parser
165 done, both for XML and HTML parsers. Use xmlCreatePushParserCtxt()
166 and xmlParseChunk() and html counterparts.
167 The tester program now has a --push option to select that parser
168 front-end. Douplicated tests to use both and check results are similar.
169
170- Most of XPath, still see some troubles and occasionnal memleaks.
171- an XML shell, allowing to traverse/manipulate an XML document with
172 a shell like interface, and using XPath for the anming syntax
173 - use of readline and history added when available
174 - the shell interface has been cleanly separated and moved to debugXML.c
175- HTML parser, should be fairly stable now
176- API to search the lang of an attribute
177- Collect IDs at parsing and maintain a table.
178 PBM: maintain the table coherency
179 PBM: how to detect ID types in absence of DtD !
180- Use it for XPath ID support
181- Add validity checking
182 Should be finished now !
183- Add regression tests with entity substitutions
184
185- External Parsed entities, either XML or external Subset [78] and [79]
186 parsing the xmllang DtD now works, so it should be sufficient for
187 most cases !
188
189- progressive reading. The entity support is a first step toward
Daniel Veillard260a68f1998-08-13 03:39:55 +0000[diff] [blame]190 asbtraction of an input stream. A large part of the context is still
191 located on the stack, moving to a state machine and putting everyting
192 in the parsing context should provide an adequate solution.
Daniel Veillardad8f99d2000-01-15 14:20:03 +0000[diff] [blame]193 => Rather than progressive parsing, give more power to the SAX-like
194 interface. Currently the DOM-like representation is built but
195 => it should be possible to define that only as a set of SAX callbacks
196 and remove the tree creation from the parser code.
197 DONE
Daniel Veillard01791d51998-07-24 19:24:09 +0000[diff] [blame]198
Daniel Veillardad8f99d2000-01-15 14:20:03 +0000[diff] [blame]199- DOM support, instead of using a proprietary in memory
200 format for the document representation, the parser should
201 call a DOM API to actually build the resulting document.
202 Then the parser becomes independent of the in-memory
203 representation of the document. Even better using RPC's
204 the parser can actually build the document in another
205 program.
206 => Work started, now the internal representation is by default
207 very near a direct DOM implementation. The DOM glue is implemented
208 as a separate module. See the GNOME gdome module.
209
Daniel Veillard01791d51998-07-24 19:24:09 +0000[diff] [blame]210- C++ support : John Ehresman <jehresma@dsg.harvard.edu>
211- Updated code to follow more recent specs, added compatibility flag
Daniel Veillard260a68f1998-08-13 03:39:55 +0000[diff] [blame]212- Better error handling, use a dedicated, overridable error
213 handling function.
214- Support for CDATA.
215- Keep track of line numbers for better error reporting.
216- Support for PI (SAX one).
Daniel Veillardad8f99d2000-01-15 14:20:03 +0000[diff] [blame]217- Support for Comments (bad, should be in ASAP, they are parsed
218 but not stored), should be configurable.
219- Improve the support of entities on save (+SAX).
