Thanks for your solution. I tested it in my application. I have a new issue
with this solution, if one of the sub menu items is empty (i.e., the
SubMenuLabel tag is empty), it still counts it and doesn't skip that if it
is empty. I tried various things but still can't skip it. I will really
appreciate if you think of how to fix that issue to skip a submenuitem node
if it is empty.
Rather than think about what you are skipping, try to focus on what you are
counting: you are counting those SubMenuLabel elements that are not
empty. When is an element not empty? When it has node children.
So, only deal with SubMenuLabel[node()] elements.
Again, the idea when working with the hierarchy is to let XSLT do the heavy
lifting by describing what it is you want done.
I hope this helps.
