I'm trying to add FB xmlns attribute to the document's `` tag (``) dynamically. For some reason adding it like below does not work: htmltag = document.getElementsByTagName ('html'); htmltag[0].setAttribute("xmlns:fb","http://www.facebook.com/2008/fbml");"); How can I do it? Thanks! Update: No jquery or other lib is available.
Who should read that attribute? XML parsers don’t interpret JavaScript.
