Excellent suggestion, thanks Charles. However, I fear that my example XML may not have illustrated my problem fully. This has made me think about the structuring though. In my real application, the sub-elements are accounts with account numbers as the attribute. Different users will be set up to view different sets of accounts and these may intersect/overlap - which potentially breaks the organisation solution you proposed. I guess my original query was "can functions like SUM() be parameterised from a list?". I imagined I would have to create a sub set into an xsl:variable and then use that. Or something. In the end I think I've decided to do this filtering upstream since I do create the XML myself. This just means that the user-specific XML document has to be created for each request - I did intend caching the full XML document (as a dom4j Java object in my Tomcat server) and then "picking out" the bits for each user. Many thanks to all who replied to my posting. Best regards, Chris XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
