Subject: [PATCH 108/139] Don't process siblings of root in xmlXIncludeProcess
|
|
|
|
xmlXIncludeDoProcess would follow the siblings of the tree root and
|
|
also expand these nodes. When using an XML reader, this could lead to
|
|
siblings of the current node being expanded without having been parsed
|
|
completely.
