This may be what your looking for:
NOTE: this is just a fragment of a class I've developed, so if you try to
compile "as-is" you will get errors. The trick your looking for is
outlined in transformToDocument method.
Just in case your wondering about the "xmlapi" namespace - I developed an
API that wraps xercesc/msxml2/libxml API's into one easy to use interface.
Toggling between vendors is just a matter of flicking a processor switch.
Nice.
