Dear All,
Using eXist database as data repository, including built in xpath and
xquery functions.
My current xquery search needs to determine the depth of the returned
node ($x) in the document - from the root.
I would then like to use this to generate the relative path that is
needed to access a node higher up the structure ($x will always be
deeper in the document).
So for example if the depth was 10, and the specific item I wished to
retrieve was at level 5, then I would want to create the relative
path: $x/../../../../../ps:specific-nodename
i.e. ( (10-5) x "/.." ) + /ps:specific-nodename (probably
done within a loop)
Below is what I have so far, but don't know how to get position or
counter to function on $x.
Can this be done without xsl? how can the relative path value be created?
TIA
