xml-dev - How to implement getElementById with Xerces?

[Bendik Vedeler <bendikv@online.no>]

According to the Xerces API it should be possible to search an entire
DOM-Document for an Element with a specific ID using
getElementById(String elementId).
The documentation states that one must somehow tell the
DOM-Implementation what the name of the id-attribute is, but says
nothing that I can see about how this is done.

I'm currently working on a large-ish project utilizing XML/XSL and
rather often need to find an Element based on it's ID, and as the
XML-documents are pretty sizeable it's really pretty wasteful to search
through the DOM-Document everytime, so if anyone knows how to do this
I'd be very grateful if you'd let me know.
