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.
This option would allow for a smaller, but mostly useless minimal build.
But it complicates the symbol availability logic in an insane way and
requires specialized tools like our custom C parser in doc/apibuild.py.
See #717.
Throw an error if entity substitution was requested.
Now we only downgrade to a warning if
- XML_PARSE_DTDLOAD wasn't specified, and
- entity aren't substituted or XML_PARSE_NO_XXE was specified.
Should fix#724.
Only fragment identifiers are an error.
This removes the last user of xmlErrMsg*. Now every error reported by
the parser should result in one of ctxt->wellFormed, ctxt->nsWellFormed
or ctxt->valid being set to zero.
This should only be done in xmlParseReference.
The handling of undeclared entities is still somewhat inconsistent. In
element content we create references even if entity substitution is
enabled. In attribute values undeclared entities are always ignored.
Always use XML_WAR_UNDECLARED_ENTITY with warning error level in
documents with external subset or parameter entities. Use
XML_ERR_UNDECLARED_ENTITY otherwise.
Also decode entities in namespace URIs if entity substitution wasn't
requested. This should fix some corner cases when comparing namespace
URIs. The Namespaces in XML 1.0 spec says:
> In a namespace declaration, the URI reference is the normalized value
> of the attribute, so replacement of XML character and entity
> references has already been done before any comparison.
Make the serialization code escape special characters in namespace URIs
like in attribute values. This fixes serialization if entities were
substituted when parsing.
Fixes https://gitlab.gnome.org/GNOME/libxslt/-/issues/106
Fixes a regression from commit e0dd330b, resulting in duplicate
attributes in the predefined XML namespace not being detected or
extraneous default attributes being passed.
Fixes#704.
Account for the full size of the entity if parsing stops because of
errors. In our cost model, we have to assume that the entity loader
processes the whole entity regardless of its content.
