I'm using version 0.8 of PyXML.
And the parser is chosen by the Reader class. I tried validating and
non-validating, so it should be pyexpat and xmlproc.
First I tought, an ENTITY Node could be created through the callback
function of the EntityResolver : resolveEntity of SAX. But this function
is called only for external entities,
right? And the DTDHandler functions aren't called neither for the
entities I'm intersted in.

Are there other solutions to build a DOM -tree than using SAX API?
Or is the native parser interface the solution?

As I stated earlier, I just started using Python and using all its XML
extensions. I'm still on the surface ;-)
Thanks for your help!
