---|
12 | DOCS: |
---|
13 | ===== |
---|
14 | |
---|
15 | - use case of using XInclude to load for example a description. |
---|
16 | order document + product base -(XSLT)-> quote with XIncludes |
---|
17 | | |
---|
18 | HTML output with description of parts <---(XSLT)-- |
---|
19 | |
---|
20 | TODO: |
---|
21 | ===== |
---|
22 | - XInclude at the SAX level (libSRVG) |
---|
23 | - fix the C code prototype to bring back doc/libxml-undocumented.txt |
---|
24 | to a reasonable level |
---|
25 | - Computation of base when HTTP redirect occurs, might affect HTTP |
---|
26 | interfaces. |
---|
27 | - Computation of base in XInclude. Relativization of URIs. |
---|
28 | - listing all attributes in a node. |
---|
29 | - Better checking of external parsed entities TAG 1234 |
---|
30 | - Go through erratas and do the cleanup. |
---|
31 | http://www.w3.org/XML/xml-19980210-errata ... started ... |
---|
32 | - jamesh suggestion: SAX like functions to save a document ie. call a |
---|
33 | function to open a new element with given attributes, write character |
---|
34 | data, close last element, etc |
---|
35 | + inversted SAX, initial patch in April 2002 archives. |
---|
36 | - htmlParseDoc has parameter encoding which is not used. |
---|
37 | Function htmlCreateDocParserCtxt ignore it. |
---|
38 | - fix realloc() usage. |
---|
39 | - Stricten the UTF8 conformance (Martin Duerst): |
---|
40 | http://www.w3.org/2001/06/utf-8-test/. |
---|
41 | The bad files are in http://www.w3.org/2001/06/utf-8-wrong/. |
---|
42 | - xml:id normalized value |
---|
43 | |
---|
44 | TODO: |
---|
45 | ===== |
---|
46 | |
---|
47 | - move all string manipulation functions (xmlStrdup, xmlStrlen, etc.) to |
---|
48 | global.c. Bjorn noted that the following files depends on parser.o solely |
---|
49 | because of these string functions: entities.o, global.o, hash.o, tree.o, |
---|
50 | xmlIO.o, and xpath.o. |
---|
51 | |
---|
52 | - Optimization of tag strings allocation ? |
---|
53 | |
---|
54 | - maintain coherency of namespace when doing cut'n paste operations |
---|
55 | => the functions are coded, but need testing |
---|
56 | |
---|
57 | - function to rebuild the ID table |
---|
58 | - functions to rebuild the DTD hash tables (after DTD changes). |
---|
59 | |
---|
60 | |
---|
61 | EXTENSIONS: |
---|
62 | =========== |
---|
63 | |
---|
64 | - Tools to produce man pages from the SGML docs. |
---|
65 | |
---|
66 | - Add Xpointer recognition/API |
---|
67 | |
---|
68 | - Add Xlink recognition/API |
---|
69 | => started adding an xlink.[ch] with a unified API for XML and HTML. |
---|
70 | it's crap :-( |
---|
71 | |
---|
72 | - Implement XSchemas |
---|
73 | => Really need to be done <grin/> |
---|
74 | - datatype are complete, but structure support is very limited. |
---|
75 | |
---|
76 | - extend the shell with: |
---|
77 | - edit |
---|
78 | - load/save |
---|
79 | - mv (yum, yum, but it's harder because directories are ordered in |
---|
80 | our case, mvup and mvdown would be required) |
---|
81 | |
---|
82 | |
---|
83 | Done: |
---|
84 | ===== |
---|
85 | |
---|
86 | - Add HTML validation using the XHTML DTD |
---|
87 | - problem: do we want to keep and maintain the code for handling |
---|
88 | DTD/System ID cache directly in libxml ? |
---|
89 | => not really done that way, but there are new APIs to check elements |
---|
90 | or attributes. Otherwise XHTML validation directly ... |
---|
91 | |
---|
92 | - XML Schemas datatypes except Base64 and BinHex |
---|
93 | |
---|
94 | - Relax NG validation |
---|
95 | |
---|
96 | - XmlTextReader streaming API + validation |
---|
97 | |
---|
98 | - Add a DTD cache prefilled with xhtml DTDs and entities and a program to |
---|
99 | manage them -> like the /usr/bin/install-catalog from SGML |
---|
100 | right place seems $datadir/xmldtds |
---|
101 | Maybe this is better left to user apps |
---|
102 | => use a catalog instead , and xhtml1-dtd package |
---|
103 | |
---|
104 | - Add output to XHTML |
---|
105 | => XML serializer automatically recognize the DTd and apply the specific |
---|
106 | rules. |
---|
107 | |
---|
108 | - Fix output of <tst val="x
y"/> |
---|
109 | |
---|
110 | - compliance to XML-Namespace checking, see section 6 of |
---|
111 | http://www.w3.org/TR/REC-xml-names/ |
---|
112 | |
---|
113 | - Correct standalone checking/emitting (hard) |
---|
114 | 2.9 Standalone Document Declaration |
---|
115 | |
---|
116 | - Implement OASIS XML Catalog support |
---|
117 | http://www.oasis-open.org/committees/entity/ |
---|
118 | |
---|
119 | - Get OASIS testsuite to a more friendly result, check all the results |
---|
120 | once stable. the check-xml-test-suite.py script does this |
---|
121 | |
---|
122 | - Implement XSLT |
---|
123 | => libxslt |
---|
124 | |
---|
125 | - Finish XPath |
---|
126 | => attributes addressing troubles |
---|
127 | => defaulted attributes handling |
---|
128 | => namespace axis ? |
---|
129 | done as XSLT got debugged |
---|
130 | |
---|
131 | - bug reported by Michael Meallin on validation problems |
---|
132 | => Actually means I need to add support (and warn) for non-deterministic |
---|
133 | content model. |
---|
134 | - Handle undefined namespaces in entity contents better ... at least |
---|
135 | issue a warning |
---|
136 | - DOM needs |
---|
137 | int xmlPruneProp(xmlNodePtr node, xmlAtttrPtr attr); |
---|
138 | => done it's actually xmlRemoveProp xmlUnsetProp xmlUnsetNsProp |
---|
139 | |
---|
140 | - HTML: handling of Script and style data elements, need special code in |
---|
141 | the parser and saving functions (handling of < > " ' ...): |
---|
142 | http://www.w3.org/TR/html4/types.html#type-script |
---|
143 | Attributes are no problems since entities are accepted. |
---|
144 | - DOM needs |
---|
145 | xmlAttrPtr xmlNewDocProp(xmlDocPtr doc, const xmlChar *name, const xmlChar *value) |
---|
146 | - problem when parsing hrefs with & with the HTML parser (IRC ac) |
---|
147 | - If the internal encoding is not UTF8 saving to a given encoding doesn't |
---|
148 | work => fix to force UTF8 encoding ... |
---|
149 | done, added documentation too |
---|
150 | - Add an ASCII I/O encoder (asciiToUTF8 and UTF8Toascii) |
---|
151 | - Issue warning when using non-absolute namespaces URI. |
---|
152 | - the html parser should add <head> and <body> if they don't exist |
---|
153 | started, not finished. |
---|
154 | Done, the automatic closing is added and 3 testcases were inserted |
---|
155 | - Command to force the parser to stop parsing and ignore the rest of the file. |
---|
156 | xmlStopParser() should allow this, mostly untested |
---|
157 | - support for HTML empty attributes like <hr noshade> |
---|
158 | - plugged iconv() in for support of a large set of encodings. |
---|
159 | - xmlSwitchToEncoding() rewrite done |
---|
160 | - URI checkings (no fragments) rfc2396.txt |
---|
161 | - Added a clean mechanism for overload or added input methods: |
---|
162 | xmlRegisterInputCallbacks() |
---|
163 | - dynamically adapt the alloc entry point to use g_alloc()/g_free() |
---|
164 | if the programmer wants it: |
---|
165 | - use xmlMemSetup() to reset the routines used. |
---|
166 | - Check attribute normalization especially xmlGetProp() |
---|
167 | - Validity checking problems for NOTATIONS attributes |
---|
168 | - Validity checking problems for ENTITY ENTITIES attributes |
---|
169 | - Parsing of a well balanced chunk xmlParseBalancedChunkMemory() |
---|
170 | - URI module: validation, base, etc ... see uri.[ch] |
---|
171 | - turn tester into a generic program xmllint installed with libxml |
---|
172 | - extend validity checks to go through entities content instead of |
---|
173 | just labelling them PCDATA |
---|
174 | - Save Dtds using the children list instead of dumping the tables, |
---|
175 | order is preserved as well as comments and PIs |
---|
176 | - Wrote a notice of changes requires to go from 1.x to 2.x |
---|
177 | - make sure that all SAX callbacks are disabled if a WF error is detected |
---|
178 | - checking/handling of newline normalization |
---|
179 | http://localhost/www.xml.com/axml/target.html#sec-line-ends |
---|
180 | - correct checking of '&' '%' on entities content. |
---|
181 | - checking of PE/Nesting on entities declaration |
---|
182 | - checking/handling of xml:space |
---|
183 | - checking done. |
---|
184 | - handling done, not well tested |
---|
185 | - Language identification code, productions [33] to [38] |
---|
186 | => done, the check has been added and report WFness errors |
---|
187 | - Conditional sections in DTDs [61] to [65] |
---|
188 | => should this crap be really implemented ??? |
---|
189 | => Yep OASIS testsuite uses them |
---|
190 | - Allow parsed entities defined in the internal subset to override |
---|
191 | the ones defined in the external subset (DtD customization). |
---|
192 | => This mean that the entity content should be computed only at |
---|
193 | use time, i.e. keep the orig string only at parse time and expand |
---|
194 | only when referenced from the external subset :-( |
---|
195 | Needed for complete use of most DTD from Eve Maler |
---|
196 | - Add regression tests for all WFC errors |
---|
197 | => did some in test/WFC |
---|
198 | => added OASIS testsuite routines |
---|
199 | http://xmlsoft.org/conf/result.html |
---|
200 | |
---|
201 | - I18N: http://wap.trondheim.com/vaer/index.phtml is not XML and accepted |
---|
202 | by the XML parser, UTF-8 should be checked when there is no "encoding" |
---|
203 | declared ! |
---|
204 | - Support for UTF-8 and UTF-16 encoding |
---|
205 | => added some convertion routines provided by Martin Durst |
---|
206 | patched them, got fixes from @@@ |
---|
207 | I plan to keep everything internally as UTF-8 (or ISO-Latin-X) |
---|
208 | this is slightly more costly but more compact, and recent processors |
---|
209 | efficiency is cache related. The key for good performances is keeping |
---|
210 | the data set small, so will I. |
---|
211 | => the new progressive reading routines call the detection code |
---|
212 | is enabled, tested the ISO->UTF-8 stuff |
---|
213 | - External entities loading: |
---|
214 | - allow override by client code |
---|
215 | - make sure it is alled for all external entities referenced |
---|
216 | Done, client code should use xmlSetExternalEntityLoader() to set |
---|
217 | the default loading routine. It will be called each time an external |
---|
218 | entity entity resolution is triggered. |
---|
219 | - maintain ID coherency when removing/changing attributes |
---|
220 | The function used to deallocate attributes now check for it being an |
---|
221 | ID and removes it from the table. |
---|
222 | - push mode parsing i.e. non-blocking state based parser |
---|
223 | done, both for XML and HTML parsers. Use xmlCreatePushParserCtxt() |
---|
224 | and xmlParseChunk() and html counterparts. |
---|
225 | The tester program now has a --push option to select that parser |
---|
226 | front-end. Douplicated tests to use both and check results are similar. |
---|
227 | |
---|
228 | - Most of XPath, still see some troubles and occasionnal memleaks. |
---|
229 | - an XML shell, allowing to traverse/manipulate an XML document with |
---|
230 | a shell like interface, and using XPath for the anming syntax |
---|
231 | - use of readline and history added when available |
---|
232 | - the shell interface has been cleanly separated and moved to debugXML.c |
---|
233 | - HTML parser, should be fairly stable now |
---|
234 | - API to search the lang of an attribute |
---|
235 | - Collect IDs at parsing and maintain a table. |
---|
236 | PBM: maintain the table coherency |
---|
237 | PBM: how to detect ID types in absence of DtD ! |
---|
238 | - Use it for XPath ID support |
---|
239 | - Add validity checking |
---|
240 | Should be finished now ! |
---|
241 | - Add regression tests with entity substitutions |
---|
242 | |
---|
243 | - External Parsed entities, either XML or external Subset [78] and [79] |
---|
244 | parsing the xmllang DtD now works, so it should be sufficient for |
---|
245 | most cases ! |
---|
246 | |
---|
247 | - progressive reading. The entity support is a first step toward |
---|
248 | asbtraction of an input stream. A large part of the context is still |
---|
249 | located on the stack, moving to a state machine and putting everyting |
---|
250 | in the parsing context should provide an adequate solution. |
---|
251 | => Rather than progressive parsing, give more power to the SAX-like |
---|
252 | interface. Currently the DOM-like representation is built but |
---|
253 | => it should be possible to define that only as a set of SAX callbacks |
---|
254 | and remove the tree creation from the parser code. |
---|
255 | DONE |
---|
256 | |
---|
257 | - DOM support, instead of using a proprietary in memory |
---|
258 | format for the document representation, the parser should |
---|
259 | call a DOM API to actually build the resulting document. |
---|
260 | Then the parser becomes independent of the in-memory |
---|
261 | representation of the document. Even better using RPC's |
---|
262 | the parser can actually build the document in another |
---|
263 | program. |
---|
264 | => Work started, now the internal representation is by default |
---|
265 | very near a direct DOM implementation. The DOM glue is implemented |
---|
266 | as a separate module. See the GNOME gdome module. |
---|
267 | |
---|
268 | - C++ support : John Ehresman <jehresma@dsg.harvard.edu> |
---|
269 | - Updated code to follow more recent specs, added compatibility flag |
---|
270 | - Better error handling, use a dedicated, overridable error |
---|
271 | handling function. |
---|
272 | - Support for CDATA. |
---|
273 | - Keep track of line numbers for better error reporting. |
---|
274 | - Support for PI (SAX one). |
---|
275 | - Support for Comments (bad, should be in ASAP, they are parsed |
---|
276 | but not stored), should be configurable. |
---|
277 | - Improve the support of entities on save (+SAX). |
---|
278 | |
---|
