RE: Dynamically creating XPath expressions Help requir

The value of your variable is a string starting with the characters "../",
this string will never be equal to 1. You've missed out the crucial stage of
telling the system to treat the string as an XPath expression and evaluate
it. For this you need the xx:evaluate() extension function available in some
processors such as Saxon and Xalan.
