Repeat after me
 "There is no notion of a default namespace in an XPath query"

Okay, but I have read (under :
"Thus, the name of a node is modeled as a pair consisting of a local part and a possibly null namespace URI; this is called an expanded-name."

and things like that, but can't find your quotation.

As a result libml2 does NOT allot to define a default namespace for
an XPath context.

cannot be seclected with

it can be selected with
"//foo:bar" when the XPath context contains a namespace binding
for the foo prefix mapping to the namespace name "";.
Just do it ! There is NO other way.


I've done it, it does work now and I appreciate any help that I've got from the list, but even though I have read the specs again, I honestly didn't got it from the xpath specs that it has to be like this.
