  libxml2 parser is actually faster than copying a tree (lot of complex
reasons for that), so that may not be that bad. The problem of your
approach in general is that you try to mix what is 2 different level,
the entity one and the tree one, the entity loader is really designed
for data waiting to be parsed, otherwise use the tree APIs.
