How can I restrict the preceding axis so a found node
will have the same ancestor as the context node? Thanks.
Why don't you use the "preceding-sibling::" axis instead?
Cheers,
Dimitre

Hi,
When I am at a <fig> with no text, I want to find the previous <fig> that
has text, but only within the same ancestor group.
I am using this:
preceding::fig[.!=""][1]
This works for all of the empty <fig> elements in the first <grp>, but in
the second <grp>, it incorrectly picks up the <fig> with the 4 value from
the previous <grp>. How can I restrict the preceding axis so a found node
will have the same ancestor as the context node? Thanks.
