Subject: [PATCH] libxslt: Type confusion in xmlNode.psvi between stylesheet
and source nodes
* libxslt/functions.c:
(xsltDocumentFunctionLoadDocument):
- Implement fix suggested by Ivan Fratric. This copies the xmlDoc,
calls xsltCleanupSourceDoc() to remove pvsi fields, then adds the
xmlDoc to tctxt->docList.
- Add error handling for functions that may return NULL.
* libxslt/transform.c:
- Remove static keyword so this can be called from
xsltDocumentFunctionLoadDocument().
* libxslt/transformInternals.h: Add.
(xsltCleanupSourceDoc): Add declaration.
Fixes #139.
