Re: [basex-talk] searching for the nearest ancestor

Hi Christian,

I've been thinking about that solution too.

Thanx for your reply, Rob

Hi Rob,

I found this solution [1] but I was wondering if also a solution is possible that makes use of the ancestor being a reverse-axis[ 2].

[ 1] ( $element/ancestor::*/child::*[ @ID = $refID] ) [ last()]

You probably need two id tests:

$element/ancestor::*[*/@ID = $refID][1]/*[@ID = $refID]

I guess it depends mostly on the input if the first or second alternative will be faster.

Hope this helps, Christian
