This is becoming a FAQ, the answer is:

Not in standard XSLT: XPath expressions cannot be constructed from strings.

There are three possible solutions:
a) generate or modify the XSLT stylesheet immediately before executing it
b) use the Saxon saxon:evaluate() extension function
c) for a limited subset of cases, use constructs such as
select="*[name()=$param]"
