Yep, JavaScript has very poor XML tooling. But anyway it should be
possible to support XPath variables here.

You can either use JS XPath library (instead of native one) that
implements variable resolvers, e.g.: http://mcc.id.au/xpathjs

Alternatively you can parse XPath expression, find all variable
references, replace them with parameter value and then reconstruct back
XPath expression. It wouldn't be twoliner, but it is certainly doable.
