Object is a Node Set :
Set contains 0 nodes:

I've already tried that (but excluded it form the post)
/ > xpath //giml:widget
XPath error : Undefined namespace prefix

So does it mean, we need another shell command like e.g.
  bind ns_prefix,ns_url
which would call
  xmlXPathRegisterNs(ctxt,GITK_NS_PREFIX,GITK_NS_URL))

If not, should prepare a patch?

Ciao
