C/C++ XML Parser/Binder

We are looking for C/C++ XML parsers that a project might use (instead
of Java) to convert objects to XML and then XML to IDL (Orbix) in use
with a consumer/provider application that converts data to XML as its
canonical form.  The product should not just be a C++ parser but also a
binder - binding the C++ objects and the XML representation.

Any suggestions?

Thanks,
