[xml] Namespace issue with empty element using SAX (patch)

[Rob Richards <rrichards ctindustries net>]

I ran into an issue when an empty element declares a namespace, the 
namespace doesnt get popped off the stack correctly.
i.e.:
<root>
   <foo xmlns="abc" />
   <bar />
</root>

bar ends up in the abc namespace.

The following patch pops the namespace for empty elements.
