The general pattern is: > > count($node-set | $node) = count($node-set) > > is true only if $node is in the node set $node-set. <shhh, don't let DC read this> 'is in the nodeset' I interpreted as '$node is a member of $node-set' </sssh> I guess this works even if $node is *anywhere* in the document tree. Just so long as its been collected into $node-set by some means. > > You can make the $node-set be the children of $x: > > count($x/* | $node) = count($x/*) > > in which case you're testing whether $node is a child of $x, or you > can make the $node-set be the descendants of $x: > > count($x//* | $node) = count($x//*) > > in which case you're testing whether $node is one of the descendants > of $x. I think that's sunk in now Jeni, I'll find out next time I come to use it!
