<xsl:variable name="C" select="$A[ count( . | $B ) = count( $B ) ]"/>
The select expression selects the node subset C of node set A, composed of
any member node of A which, when added to node set B, produces a node set
the same size as B (in other words, the node was already in node set B).
The usage of A and B in the select expression can be reversed with no side
effects except possibly:
o a change in the list ordering of nodes in node set C
o a change in the speed of execution of the expression

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?.
