Re: XPath with default namespace

No, there isn't.  You must use a prefix for the default namespace.
   

I'm told XPath 2.0 is proposing to add a default-namespace mechanism.
I don't know whether they're going to do anything about my own pet peeve,
which is that there is no syntax in XPath itself for binding namespaces and
hence it's impossible to write an XPath that is completely self-contained
and portable; some (unspecified) source for the prefix-to-namespace mapping
is always required.
 

You actually can write an xpath which is completely self-contained and 
portable but its messy eg:

/ex:foo/ex:bar
can be written as:
/*[namespace-uri()='http://www.example.com/foo' and 
local-name()='bar']/*[namespace-uri()='http://www.example.com/foo' and 
local-name()='moo']

and will work anywhere :-)
