hi -

I have constructed two variables (A and B) each of which contains a Node
Set (through select="XPath Expression").

A = [Node1, Node2, Node3, Node4, Node5]
B = [Node3, Node4, Node5, Node6, Node7, Node8]

I now would like to construct another variable C with the Nodes that exist
both in A and B.  (So as to produce a third table with the Nodes that are
common to both A and B).

C= [Node3, Node4, Node5]

Is there any way to construct C from A and B?.

thanks
