Hello list,
I'm stuck again. As always I hope this is not a case of RTFM. Consider this
XML:
<po id="1">
<someelement/>
<po id="2">
<someelement>
<po id="3">
<someelement/>
</po>
</someelement>
<po id="4">
<someelement/>
</po>
</po>
</po>
For the element <po id="3"> I'd like to get the id attribute from the
ancestor that is a po Element (in this case, '2').
What I got with 'ancestor::po' was '1', the attribute from the 'eldest'
ancestor. 'parent::po' returns nothing, because obviously it isn't the
parent i am seeking. More like the grand-parent, so to speak.
In other words: I'm looking for the nearest ancestor relative who is not a
parent. And I don't want uncles, either... ;-)
Changing the xml-structure is not an option, unfortunately.
Any hints?
Thank you,
Christian
