xml-dev - Re: XML vs. object model resource usage for manipulation

["Rochelle Edens" <edensr@businesslogic.com>]

I'm actually more concerned about DOM manipulation and parsing-activities in comparison to
creating an object and method invocations.  I understand there's a lot of overlap and
instantiating objects is inherent to both, and maybe I need to dig through parser code and see
how it's working and what's getting created.  My thinking was that it could *potentially* be
an issue.

Thanks,
    Rochelle
