[xml] (python) entity loader issue

[Nic <nferrier tapsellferrier co uk>]

I'm in a situation where I'm doing some processing on XSLT documents
when they are loaded and I'm having a lot of trouble doing this
efficiently.

What I have right now is a python entity loader which:

- reads in the associated document
- parses it in memory
- processes the XSLT
- caches the dom for later


Because I'm loading the document and parsing it myself I tried (for a
while) to have the entity loader pass back the document itself.

But that didn't work.

So now I have the entity loader return an open python file handle.

Clearly that is going to mean that libxml2 duplicates my effort by
parsing the document again.


Anyway round this?
