I want is, can I copy 2 variables into one.. and
traverse the merged one, and during traversing,
somewhere can I check for some value that appears in
one variable.
You can only do thatby converting the result tree fragment containing
the merged set back into a node set using your processor's node-set
extension function, if it has such an extension.
But it depends whatyou mean by a merge, You only needed to use a result
tree fragment as you were constructing a wrapper element around the two
sets, if you don't need that you can go
<xsl:variable name="v3" select="$v1|$v2"/>
and then v3 is the union of v1 and v2.
