After some more investigations, I have found that XPath namespaces must be predeclared.
If the declaration is on the top-level element, then xalan does seem to pick up the definition (provided that namespaces are enabled, which is not currently the case in the XPath extractor). However namespaces that are declared on child elements are not available to XPath. This is because there can be multiple declarations of the same namespace - and these can use different URIs. It may be possible to enhance the XPath extractor to allow the user to provide a namespace declaration; this would simplify the writing of the XPath. I.e. instead of XPath: //*[local-name()='result' and namespace-uri()='http://biz.aol.com/schema/2006-12-18' ] the idea is that you would be able to use: Namespace declaration: ns http://biz.aol.com/schema/2006-12-18 XPath: //ns:result But this will have to wait for a future JMeter release.
