  Hum, I can't remember an API for doing this, I don't think this exists.
This is close to the discussion we had a couple of months ago about 
xmlNodeGetContent() in the case of entities and how to handle the recursion
but I doubt there is code reusable as is, sorry.
  This would also lack the DTD attributes defaulting needed for the XPath
data model.
