| 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 | ===== |
---|
[20734] | 22 | - XInclude at the SAX level (libSRVG) |
---|
[17095] | 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. |
---|
[20734] | 27 | - Computation of base in XInclude. Relativization of URIs. |
---|
[17095] | 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 |
---|
[18209] | 35 | + inversted SAX, initial patch in April 2002 archives. |
---|
[17095] | 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/. |
---|
[21531] | 42 | - xml:id normalized value |

[17095] | 43 | |
---|
| 44 | TODO: |
---|
| 45 | ===== |
---|
| 46 | |
---|
[18209] | 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. |
---|
[17095] | 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/> |
---|
[20734] | 74 | - datatype are complete, but structure support is very limited. |
---|
[17095] | 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 | |
---|
[20734] | 82 | |
---|
| 83 | Done: |
---|
| 84 | ===== |
---|
| 85 | |
---|
[17095] | 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 ? |
---|
[20734] | 89 | => not really done that way, but there are new APIs to check elements |
---|
| 90 | or attributes. Otherwise XHTML validation directly ... |
---|
[17095] | 91 | |
---|
[20734] | 92 | - XML Schemas datatypes except Base64 and BinHex |
---|
| 93 | |
---|
| 94 | - Relax NG validation |
---|
| 95 | |
---|
| 96 | - XmlTextReader streaming API + validation |
---|
| 97 | |
---|
[17095] | 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 |
---|
[20734] | 102 | => use a catalog instead , and xhtml1-dtd package |
---|
[17095] | 103 | |
---|
[20734] | 104 | - Add output to XHTML |
---|
| 105 | => XML serializer automatically recognize the DTd and apply the specific |
---|
| 106 | rules. |
---|
[17095] | 107 | |
---|
[20734] | 108 | - Fix output of <tst val="x
y"/> |
---|
[17095] | 109 | |
---|
[20734] | 110 | - compliance to XML-Namespace checking, see section 6 of |
---|
| 111 | http://www.w3.org/TR/REC-xml-names/ |
---|
[17095] | 112 | |
---|
[20734] | 113 | - Correct standalone checking/emitting (hard) |
---|
| 114 | 2.9 Standalone Document Declaration |
---|
| 115 | |
---|
[18209] | 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 | |
---|
[17095] | 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 | |
---|
