You need to declare the namespace in your XSLT, and use it in XPath expressions. E.g.:

    ... 

Note that you must provide some prefix if you want to refer to elements from that namespace in XPath. While you can just do xmlns="..." without the prefix, and it will work for literal result elements, it won't work for XPath - in XPath, an unprefixed name is always considered to be in namespace with blank URI, regardless of any xmlns="..." in scope.
