Test XPath expressions with namespaces in Chrome

Question

I have a XML document opened in Chrome and I would like to test some XPath expressions. The XML document involves different namespaces. How do I define the prefix URIs?

For testing XPath expressions in Chrome I have used $x("...") so far.

What Chrome extension are you using to enter the XPath expressions? — Wim Ombelets, Jan 08 '13 at 19:05

If you searched for an element "description" anywhere inside the XML document, you could use the local-name() function. Example:

$x("//*[local-name()='description']")
