Need to learn how to set up the context in Xerces-C and/or XQuilla

[Ramon F Herrera <ra...@patriot.net>]

I have been using two XPath implementations, the one from Xerces-C (for 
fast performance) and XQilla (for full expression support).

At this point I have some expressions that must be evaluated in two steps.

First query:

/root/table[@tagname='intermediate_joints']

The tables produced by that query should be set as the new context 
before the next XPath queries are performed.

How do I set up the context?

TIA,
