No, the way you have done it is the correct way. It's rather verbose, but
it's conceptually simple, and by writing it you have learnt a powerful and
extensible technique.

You're really asking here for first-class functions or lambda expressions,
something that is the subject of some of the heavy theoretical discussion on
this list that you're probably ignoring and dismissing as irrelevant.

Meanwhile you could play with the evaluate() extension function available in
Saxon, Xalan, etc.
