How does the example XUL exactly look?
XUL is XML and XUL elements are in the XUL namespace (and HTML elements 
in the XHTML namespace probably if HTML elements are used inside of XUL 
docs) so you likely need to make sure your resolver correctly resolves 
the namespaces and your XPath expression uses namespace prefixes even if 
the elements are in the default namespace (e.g. <window xmlns="...">) as 
XPath expression don't know about default namespaces meaning
   window
as an XPath expression matches <window> elements (null namespace) but 
not <window xmlns="http://example.com/2005/02/ws"> for instance, for 
that you need to make sure you use a prefix in your XPath bound to the 
namespace URI e.g. if your resolver resolves 'ws' to 
'http://example.com/2005/02/ws' then the XPath
   ws:window
matches.
