You know, I've been sitting in the weeds watching the discussion. If I had to vote (and I did on an earlier poll), I would have voted for returning null. But Elliotte's point above suddenly hit me and I think (I'm not totally positive yet!) that Mr. Harold is actually right. It appears to be too late since vote was taken, but the combination of Element.hasAttribute(String) and Element.getAttribute(String) throws NoSuchAttributeException might actually have been the wiser course. AAGGHH, my whole worldview is falling to pieces around me! I might have to retreat to my cubbyhole with the XPath recommendation and some oxygen! AGGHH!! 8-)
Humour aside, I think Elliotte's point above is a very good and it's too bad that he didn't express it so clearly a week ago.
