I've knocked up a patch for python wrapping the xslt loader API. 

My patch facilitates writing loaders in python.

But I'm having problems getting the xmlDocPtr back from a python
When I do this I don't seem to get a valid doc.

The python I'm using is:

 def fn(url, ctx):
        # print url
        ctxt = libxml2.parserCtxt(_obj=ctx)
        doc = ctxt.ctxtReadDoc("""<?xml version='1.0'?><b/>""", url, "UTF-8", 0)
        return doc

  The C object wrapper is in doc._o, maybe you don't want to have the function
return it, in that case at the C level you may have to grab the _o 
    except Exception, e:
        print >>sys.stderr, "something went wrong:", e
        return None

The return value of ctxtReadDoc is a PyCObject wrapped xmlDocPtr so I
presumed that I'd just be able to access it with PyxmlNode_Get. But as
I say... this is not so.

  I think there is one more layer :-) sorry for the complexity ...

Anybody know what mantra I need to get at the doc object returned from
python in this instance?

  lookup the _o, see especially the xmlDoc constructor.
