    This is nice syntax for both parsing and xquery.

    I'd suggest syntax that returns an axis as well.

    axis decendent_or_self = xmldom[ L"/xml/foo" ].decendent_or_self;
    for (i = decendent_or_self.begin(); i != decendent_or_self.end(); i++) 
    {
        node n = *i;
        if (n.namespace_uri() != null)
        {
            std::cout << n.namespace_uri() << "\n";
        }
    }

    Excuse my C++. I'm rusty.
