RE: dynamic variable name/implementation question

ok.  I see.
My goal here is to be able to pass in dynamic data to a transformation
that is part of a web application.  I was just using xalan to unit test
the exsl:node-set(), but am using php/sablotron for the app.  Does
anyone know of a way to get dynamic run-time data into a stylesheet
using php/sablotron?  That is, without the stylesheet knowing the name
of the parameter, but rather can be specified in the source document?
I don't beleive using the document() function would work to retrive the
result of a php script as XML, because calling a php page from within
sablotron would probably just return the source, not the executed
output, correct?
