Xerces DOM Objects & Xalan

[Gupta, Rajan]

Hello! All,
I have a design question on using Xalan with DOM Documents generated via
Xerces. How can I apply an XPath expression on a DOM_Document as defined in
<dom/DOM_Document.hpp>

I notice in the samples provided that Xalan uses its DOM hierarchy such as
XalanDocument. Was there any specific reason not to use the objects defined
by Xerces or I am missing something.

Thanks
Rajan
