You can count the number of nodes in a node set using count(). If the
context node is a Wrapper element, then you can count how many child
elements it has with:
count(*)
And you can compare this number to 2 with:
count(*) > 2
So, you can pick the Wrapper elements for which this is true with:
Wrapper[count(*) > 2]
I hope that helps,
Jeni
