RE: [xsl] Evaluate string as XPATH axis in XSLT1.0?

There's no standard way to construct an XPath expression from a string at
run-time in either XSLT 1.0 or 2.0. 

Some products have an extension to do this, for example saxon:evaluate().

If you want a portable solution, the only way around it is to generate a
stylesheet.
