Subject: Re: [PHP-DEV] Simplexml and xml namespaces
From: sterling.hughes@gmail.com (Sterling Hughes)

Hm - that shouldn't be. =20

I think the right solution is that media:title should not show up in
the children of node, unless you are looking at the proper namespace,
ie, you need to use children() to get the children in that namespace.
