| 97 | manage them -> like the /usr/bin/install-catalog from SGML |
| 98 | right place seems $datadir/xmldtds |

Daniel Veillard | 32bc74e | 2000-07-14 14:49:25 +0000 | [diff] [blame] | 154 | xmlStopParser() should allow this, mostly untested |
Daniel Veillard | be80396 | 2000-06-28 23:40:59 +0000 | [diff] [blame] | 155 | - support for HTML empty attributes like <hr noshade> |

| 157 | - xmlSwitchToEncoding() rewrite done |
Daniel Veillard | 496a1cf | 2000-05-03 14:20:55 +0000 | [diff] [blame] | 158 | - URI checkings (no fragments) rfc2396.txt |

Daniel Veillard | 361d845 | 2000-04-03 19:48:13 +0000 | [diff] [blame] | 161 | - dynamically adapt the alloc entry point to use g_alloc()/g_free() |
| 162 | if the programmer wants it: |
| 163 | - use xmlMemSetup() to reset the routines used. |
| 164 | - Check attribute normalization especially xmlGetProp() |
| 165 | - Validity checking problems for NOTATIONS attributes |
| 166 | - Validity checking problems for ENTITY ENTITIES attributes |
| 167 | - Parsing of a well balanced chunk xmlParseBalancedChunkMemory() |
| 168 | - URI module: validation, base, etc ... see uri.[ch] |
| 169 | - turn tester into a generic program xmllint installed with libxml |
Daniel Veillard | ec30341 | 2000-03-24 13:41:54 +0000 | [diff] [blame] | 170 | - extend validity checks to go through entities content instead of |
| 171 | just labelling them PCDATA |
Daniel Veillard | 75c2921 | 2000-03-14 18:33:47 +0000 | [diff] [blame] | 172 | - Save Dtds using the children list instead of dumping the tables, |
| 173 | order is preserved as well as comments and PIs |
| 174 | - Wrote a notice of changes requires to go from 1.x to 2.x |
| 175 | - make sure that all SAX callbacks are disabled if a WF error is detected |
| 176 | - checking/handling of newline normalization |
| 177 | http://localhost/www.xml.com/axml/target.html#sec-line-ends |
| 178 | - correct checking of '&' '%' on entities content. |
| 179 | - checking of PE/Nesting on entities declaration |
| 180 | - checking/handling of xml:space |
| 181 | - checking done. |
| 182 | - handling done, not well tested |
| 183 | - Language identification code, productions [33] to [38] |
| 184 | => done, the check has been added and report WFness errors |
| 185 | - Conditional sections in DTDs [61] to [65] |
| 186 | => should this crap be really implemented ??? |
| 187 | => Yep OASIS testsuite uses them |
| 188 | - Allow parsed entities defined in the internal subset to override |
| 189 | the ones defined in the external subset (DtD customization). |
| 190 | => This mean that the entity content should be computed only at |
| 191 | use time, i.e. keep the orig string only at parse time and expand |
| 192 | only when referenced from the external subset :-( |
| 193 | Needed for complete use of most DTD from Eve Maler |
| 194 | - Add regression tests for all WFC errors |
| 195 | => did some in test/WFC |
| 196 | => added OASIS testsuite routines |
| 197 | http://xmlsoft.org/conf/result.html |
| 198 | |
| 199 | - I18N: http://wap.trondheim.com/vaer/index.phtml is not XML and accepted |
| 200 | by the XML parser, UTF-8 should be checked when there is no "encoding" |
| 201 | declared ! |
| 202 | - Support for UTF-8 and UTF-16 encoding |
| 203 | => added some convertion routines provided by Martin Durst |
| 204 | patched them, got fixes from @@@ |
| 205 | I plan to keep everything internally as UTF-8 (or ISO-Latin-X) |
| 206 | this is slightly more costly but more compact, and recent processors |
| 207 | efficiency is cache related. The key for good performances is keeping |
| 208 | the data set small, so will I. |
| 209 | => the new progressive reading routines call the detection code |
| 210 | is enabled, tested the ISO->UTF-8 stuff |
Daniel Veillard | ad8f99d | 2000-01-15 14:20:03 +0000 | [diff] [blame] | 211 | - External entities loading: |
| 212 | - allow override by client code |
| 213 | - make sure it is alled for all external entities referenced |
| 214 | Done, client code should use xmlSetExternalEntityLoader() to set |
| 215 | the default loading routine. It will be called each time an external |
| 216 | entity entity resolution is triggered. |
| 217 | - maintain ID coherency when removing/changing attributes |
| 218 | The function used to deallocate attributes now check for it being an |
| 219 | ID and removes it from the table. |
| 220 | - push mode parsing i.e. non-blocking state based parser |
| 221 | done, both for XML and HTML parsers. Use xmlCreatePushParserCtxt() |
| 222 | and xmlParseChunk() and html counterparts. |
| 223 | The tester program now has a --push option to select that parser |
| 224 | front-end. Douplicated tests to use both and check results are similar. |
| 225 | |
| 226 | - Most of XPath, still see some troubles and occasionnal memleaks. |
| 227 | - an XML shell, allowing to traverse/manipulate an XML document with |
| 228 | a shell like interface, and using XPath for the anming syntax |
| 229 | - use of readline and history added when available |
| 230 | - the shell interface has been cleanly separated and moved to debugXML.c |
| 231 | - HTML parser, should be fairly stable now |
| 232 | - API to search the lang of an attribute |
| 233 | - Collect IDs at parsing and maintain a table. |
| 234 | PBM: maintain the table coherency |
| 235 | PBM: how to detect ID types in absence of DtD ! |
| 236 | - Use it for XPath ID support |
| 237 | - Add validity checking |
| 238 | Should be finished now ! |
| 239 | - Add regression tests with entity substitutions |
| 240 | |
| 241 | - External Parsed entities, either XML or external Subset [78] and [79] |
| 242 | parsing the xmllang DtD now works, so it should be sufficient for |
| 243 | most cases ! |
| 244 | |
| 245 | - progressive reading. The entity support is a first step toward |
Daniel Veillard | 260a68f | 1998-08-13 03:39:55 +0000 | [diff] [blame] | 246 | asbtraction of an input stream. A large part of the context is still |
| 247 | located on the stack, moving to a state machine and putting everyting |
| 248 | in the parsing context should provide an adequate solution. |
Daniel Veillard | ad8f99d | 2000-01-15 14:20:03 +0000 | [diff] [blame] | 249 | => Rather than progressive parsing, give more power to the SAX-like |
| 250 | interface. Currently the DOM-like representation is built but |
| 251 | => it should be possible to define that only as a set of SAX callbacks |
| 252 | and remove the tree creation from the parser code. |
| 253 | DONE |

Daniel Veillard | ad8f99d | 2000-01-15 14:20:03 +0000 | [diff] [blame] | 255 | - DOM support, instead of using a proprietary in memory |
| 256 | format for the document representation, the parser should |
| 257 | call a DOM API to actually build the resulting document. |
| 258 | Then the parser becomes independent of the in-memory |
| 259 | representation of the document. Even better using RPC's |
| 260 | the parser can actually build the document in another |
| 261 | program. |
| 262 | => Work started, now the internal representation is by default |
| 263 | very near a direct DOM implementation. The DOM glue is implemented |
| 264 | as a separate module. See the GNOME gdome module. |
