No, sorry for being unclear.  I mean that from the set of ip attributes
on the axis which contains both the root and the required id attribute:

  / ... @ip ... @ip ... @ip ... @id

I want to find the left-most one in the above diagram, nearest to the root
(or to other selected starting node inbetween the root and the required @id).

I can do this for single ids with the Xpath query I posted, although I
don't fully understand the ordering I am getting.  I can't figure out
how to make a satisfactory query which will return the set of leftmost
@ip for all the ids in the XML document.

Thanks for your interest, if I'm still not explaining clearly please let
me know.  I'm quite new to XML/Xpath and don't always know the correct
way to describe what I want to do.
