Summary: XML::Node.empty? always return false!?
Initial Comment:
It seems that Node.empty? always return false. Or maybe my definition for an
empty node was wrong.
Example code:
XML::Node.new('name').empty? #=> false
I'm using ruby 1.9.2 and libxml-ruby 1.1.4.

Message:
Actually, the code is correct but the documentation is wrong. From LibXML docs
for xmlIsBlankNode (the underlying method).
"Checks whether this node is an empty or whitespace only (and possibly
ignorable) text-node."
So empty? is only true for text nodes. Docs have been updated.
Thanks - Charlie
