I can't follow you. Usually if you have an XPathExpression object, then you don't use it with XSLT but rather with the XPathNavigator API where you can pass in an XPathExpression to the Select or SelectSingleNode method. If you are doing something else then please show us the relevant code to enable us to understand how exactly you use XPathExpression. -- Martin Honnen --- MVP XML http://JavaScript.FAQTs.com/ | |
