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(*) &gt; 2

So, you can pick the Wrapper elements for which this is true with:

  Wrapper[count(*) &gt; 2]

I hope that helps,

Jeni
