In my case the XML document containing variable number of xslt parameters never exists as a file (my fault, in I've written 'XML _file_', but should have 'XML _document_', sorry). It's generated by one application as an XML, and then passed via tcp socket to another application which performs XSL transformation, then returns results (in the form of XML document on tcp as well) to the first one. So I can't pass URL of an XML _file_ as a parameter because no such a _file_ exists. Of course I could save this XML as a temporary file and then use it's URL (as you have explained) but it's not a convenient solution for me. So I would be grateful for further help. -- Greetings Jarek Lubczynski There are 10 kinds of people: Those who understand binary and those who don't
