true, however libgdome is provided as a rpm, and it should be possible to 
generate a libgdome dll for windows.

Well libgdome is working towards strict DOM compliance, and you'll have
a great head start.  It is currently mostly compliant with DOM Level 2.

libgdome uses the _private member of the libxml structures to store
a references to the wrapper object, so there is at most one libgdome 
object per libxml object.

if you decide to continue to work on the libxml wrapper, it might also be 
useful for you to check out XML::LibXML (Perl wrapper to libxml).  See
