Benjamin Schulz 07 December 2006 saski: You don’t have to insert a “tag” (processing instruction). When your browser comes across the processing instruction it starts up an instance of its XSLT-Processor and passes in both the stylesheet and your XML-Document. That is exactly what you have to do. The question is, which language do you use?? Check out http://php.net/xsl – it should demonstrate the concept.
