-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.
