I am already looping through this XML at the level of /Section/Event/Content. Using xpath for each Content event I need to select the all the successive (following) content elements until I meet an element that meets the following condition:

The element contains the attribute ownRow="1" or they are a descendant of an event with the attribute sense=Audio".

I have tried and tried without success... My closest attempt:


using ns1[count(.| ns2)=count(ns2)]

ns1 = following::Event

ns2 = following::Event/Content[not(@ownRow=1) and not(following::Event[1][@sense='Audio'])]/preceding::Event

Which makes this:


following::Event[count(.| following::Event/Content[not(@ownRow=1) and not(following::Event[1][@sense='Audio'])]/preceding::Event)=count(following::Event/Content[not(@ownRow=1) and not(following::Event[1][@sense='Audio'])]/preceding::Event)]/Content/@renderValue"/>"

But it does not pick up the 4th CAPTION - can't figure out why?
