Converting XML to an Escacped URL

Hi there,

I was attempting to convert an XML document into an escaped URL to
send over a HTTP get and couldn't find a very good solution and was
wondering if anyone has designed or had any thoughts to the design of
a stylesheet that could do this. I don't mind if I use version 1.0 or
2.0. I figured that a character map might be the answer for any spaces
but I'm still not certain how I can change tags into escaped
characters unless there is a good way to get a nodeset as a string
then use escape-uri on it.

Thanks,

Gary
