Well, you can either use the magic of Copy & Paste, or you can do some fancy footwork with EXSLT. I don't think Copy&Paste needs any explanation. With EXSLT (http://www.exslt.org) you could probably use the eval() function to create an XPath expression and evaluate it, to perform your test. At this point however, I think it might be worth taking a step back and trying to determine what you're getting done, and perhaps refactor what you're doing, instead of trying to force the XSL params functionality into place. Perl-space would be a good spot to look for that. - -- Michael A.
