OK, here it is. I have attached two example XML files - one with a
namespace declared on the root node (test-ns.xml), and one without
(test-nons.xml). This is the only difference between them.

Here's what I get for them. Everything's just as expected, except that
the first find should return 2 as well.

$ irb
irb(main):001:0> require 'xml/libxml'
=> true
irb(main):002:0>
XML::Document.file('test-ns.xml').find('nodes/subnode').size
        => 0
irb(main):003:0>
XML::Document.file('test-nons.xml').find('nodes/subnode').size
=> 2
irb(main):004:0>
XML::Document.file('test-ns.xml').find('myns:nodes/myns:subnode',
'myns:http://some-ns.com/').size
=> 2

The docs here say that if I don't specify a namespace on the search,
then any NS may be matched:

As a side note, the API Docs link is broken on the new front page,
taht's why I included this cached copy.
