Q for XML XSL Pros

[coganH]

How can I get the full xpath of the XML nodes from the
XSL file which is reading it?
I am working with an htc file which needs to update
an XML object. The htc file reads from another
XML object which contains the same nodes. These
nodes are not placed at the same order as the first object and I need to know the exact xPath of the node.
Is this enough info, or should I paste the files, as well?

THANKS!!
