This goes back to the idea of the union ignoring duplicates (count only once)? hence count($x//*|$y) = count($x//*) implies that node $y is a member of the set which is all the children of $x? Is that right? Still doesn't resolve my original problem though. the hierarchy above is level1 level2 level3 I'm looking for *immediate* descendent, i.e. level3 (and hence note) are not *immediate* descendents of level1, level2 intervenes. I'm playing with Dimitres suggestion, along the lines of var myNearestParentLevel = substring-after(ancestor-or-self(contains (name('level')) ... i.e. get '3' for note as being the nearest wrapper. then use Dimitres ideas to check if (for level1) l+1 = $myNearestParentLevel which is false.
