RE: [xml-dev] Xsl:when - Can I pass Conditions at runtime?

XSLT doesn't have any mechanism to evaluate an XPath expression which is
supplied at run-time in the form of a string. (I fought hard to get this
into XSLT 2.0 and failed...)

If the XPath expression is simply an element name, you can use
test="*[name()=$param]".

For more general expressions, you need an extension like saxon:evaluate().

I find that serious XSLT applications use this kind of extension all the
time.
