Subject: Re: libxml-ruby namespace problem

Follow-up to myself:

Actually, libxml-ruby won't find what I'm looking for if either a
namespace or a DOCTYPE declaration is present in the document. I had to
remove both to get results.

If I have only the DOCTYPE in the document, it doesn't raise an
exception for e.g. the document not conforming to the specified DTD, it
just returns empty result sets.
