Note that if a default namespace for elements has been set up, then the only way to select those elements whose namespace URI is null is to include a predicate that tests the result of the
namespace-uri()
function.

Examples of Name Tests

Expression	Description
*	Matches any name. If * is used on its own, it represents the step child::* , which selects all child elements of the context node, regardless of their name.
xt:*	Matches any name in the namespace bound to the prefix xt . If xt:* is used on its own, it represents the step child::xt:* , which selects all child elements of the context node that are in the namespace bound to the prefix xt .
title	Matches a node whose local name is name title and whose namespace URI is null, unless a default namespace for elements has been established in the context (and then, only when the axis is not the attribute or namespace axis).
