  Actually, what you want to do is using a string expression extracted
from your XML input as an XPath inside your XSLT code to select nodes
inside another XML input.

  This is not possible with standard XSLT instructions and XPath
functions. Nevertheless, you can use an extension function to do this :
  - in exslt: dyn:evaluate(string) (see following address for details:
http://www.exslt.org/dyn/functions/evaluate/index.html ). But, the problem
could be that your favorite XSL processor doesn't implement this function.
  - if your favorite processor is 4xslt, you can use 4Suite extension
function called ft:evaluate(string) (see following address for details:
http://www.4suite.org/4Suite.org/documents/4Suite/4XPath-Extensions#evaluat=
e
).

  Hoping this will help,
