2: 124110 DTD validation && wrong namespace
3: 123564 xmllint --html --format

5: TODO for the XML parser and stuff:
6: ==================================
7:
8: $Id$
9:
10: this tend to be outdated :-\ ...
11:
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).
