The problem is your expectation that it will be different every time. In a functional language, giving the same arguments to a function should always produce the same result. The XSLT spec also explicitly states, in the section about document(), "Two documents are treated as the same document if they are identified by the same URI". Have you investigated what it would take to extend the URI resolver class that your XSLT processor uses? This varies from processor to processor, but if you can do that, then you could make your own URI scheme, and have your resolver process your custom URIs as necessary. The main thing the class need to do is find the right document and return it as a stream. Check your processor docs. - Mike ____________________________________________________________________________ mike j. brown | xml/xslt: http://skew.org/xml/ denver/boulder, colorado, usa | resume: http://skew.org/~mike/resume/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
