You just need a very simple Java servlet or ASP page that accepts the
parameters and passes them to the stylesheet. There are example servlets
that do this distributed with several of the XSLT processors.

msxsl:script is evaluated at transformation time, not at
display/interaction time. Event handlers like this should be part of the
HTML page that you generate, not part of the stylesheet used to generate
it.

See the Microsoft documentation.

If you are using the Microsoft product, then msxsl:script is the way
that you define Javascript functions to be invoked from your
transformation code.
