what do you mean by "obtain" here?

You refer to sets of nodes so I think you are using xpath1. nodeset is
the only type available there which can't really model this (unless you
copy all the nodes into an xml focument representing the product).

Xpath2 has sequences of nodes, but again you can't really model the
product of sequences as you can't have sequences of sequences.

in xslt1 and 2 though you can of course effectively iterate over all the
items in the product just by having nested for-each loops which
iterates over each set, and for most purposes, this is enough...
