You don't say what data type these variables are, but nevertheless the XPath syntax only allows node set variable references in the first step of a location path.


it didnt work, does anyone know another way of doing it? or is it doable at
all?

It is not doable at all using standard W3C XSLT 1.0.


If the data types of these two variables are both strings, there are some vendor extensions that will translate a string into an XPath address and return node sets ... but these are not portable. There are also such functions in the http://www.exslt.org project that may be supported by a wider set of vendors.

I hope this helps.
