A quick follo-up: you probably allready found this, but just in case
others are interested:

 http://extrememarkup.com/extreme/2001/ExtremeWeb/html/p0014.htm

Gives some information on GDome implementation and compares GDome to Xerces.
BTW, there's no such thing as a DOM parser. DOM is an API (more specific,
the definition of a set of functions operating on a document). GDome provides
a mapping of this API to libxmls 'native' functions (libxml has it's own
idea of a document. If you don't need to be DOMpatible it's a nice and lean 
lternative). Oh, and just to add to the confusion: the document model of
XSL(T) - even so designed by the same institution as DOM, is slightly different
from both DOMs and libxmls ....
