Given the following XML, how do I write an XPath query to pull nodes where the attribute foo
exists?:
<node1>
<node2>
<node3 foo='bar'></node3>
<node3></node3>
<node3 bar='foo'></node3>
<node3 foo='foobar'></node3>
</node2>
</node1>

Short and sweet:
//*[@foo]
Of course you should use a more specific expression. But with [@attributeName]
you get all nodes which have that attribute.
