The following strings are never allocated from a dict:
- xmlParserCtxt.version
- xmlParserCtxt.encoding
- xmlParserCtxt.extSubURI
- xmlParserCtxt.extSubSystem
- xmlDoc.version
- xmlDoc.encoding
- xmlDoc.URL
- xmlDTD.ExternalID
- xmlDTD.SystemID
- xmlID.value
Also make the struct members point to non-const chars to avoid casts
when freeing.
At some point, the `loadsubset` member was augmented to also control
handling of ID attributes in addition to loading of external DTDs. These
two features are unrelated and shouldn't have been mixed. This mistake
was probably inspired by the misnamed XML_DETECT_IDS flag. As a side
effect, setting XML_SKIP_IDS always enabled loading of external DTDs and
parameter entities.
This change makes it possible to ignore IDs without loading external
content. This is a deliberate API change that improves security and is
unlikely to affect users.
This also makes sure that the new XML_PARSE_SKIP_IDS option doesn't
enable unsafe behavior.
Also clean up catalog resolution and add error handling using the
global error.
Don't try to look up the resolved URI a second time.
Add some comments. Fix documentation.
Fix many params in internal functions (not really necessary but Doxygen
warns about that in XML mode).
Fix formatting in a few corner cases that automatic conversion can't
handle.
Rearrange some DOC_DISABLE blocks.
Support for RELAX NG used to be enabled together with XML Schema support
(--with-schemas). Now there's a separate option and a new feature macro
LIBXML_RELAXNG_ENABLED.
Add a new parser option XML_PARSE_UNZIP that enables decompression.
xmlReadFile, xmlCtxtReadFile and xmlCreateURLParserCtxt always set
this option currently, but downstream users should start to set the
option if they really need it.
This was only used by Chromium/WebKit to detect whether xmlParseContent
really succeeded. It's a horrible, overcomplicated hack.
See 8c5848bd and #767.
This implements xmlCtxtParseContent, a better alternative to
xmlParseInNodeContext or xmlParseBalancedChunkMemory. It accepts a
parser context and a parser input, making it a lot more versatile.
xmlParseInNodeContext is now implemented in terms of
xmlCtxtParseContent. This makes sure that xmlParseInNodeContext never
modifies the target document, improving thread safety.
xmlParseInNodeContext is also more lenient now with regard to undeclared
entities.
Fixes#727.
- xmlKeepBlanksDefault is needed as a work-around for
xmlParseBalancedChunk, see issue #727.
- ctxt->options already has an accessor and will be deprecated
later.
- input->cur, input->base, input->end: See #762.
