Re: Relative XPATH between 2 nodes

This can be achieved in two different ways:

  1. Having the two nodes, then finding their first common ancestor up
in the hierarchy, then constructing the path down to the second node
from the common ancestor. This is straightforward.

  2. Using the strings (the XPath expressions ) for the two nodes.
This is much harder. For a similar solution for filenames in a tree
filesystem see:
