This is an XPath FAQ. Without a ns prefix, XPath doesn't choose elements living in the default ns, but ones living in no namespace.
Are there any good references you might point me to? I'm pretty new to this stuff and beyond my "in a Nutshell" book don't have many places to consult yet.

And /root/foo/qxx? Do you select qxx in the default ns? Or not?

That makes perfect sense. I'm realizing that XPaths are not as portable as I thought they were. At least not without some way of converting element prefixes easily...
You just have to learn that prefixes are just aliases to the real namespaces, then you're fine. Don't count on prefixes, they itself are meaninngless. And always use registerNamespace() for all namespaces you need in the XPath query. Then XPath is very portable.
