merge an empty <a> with text in a <span>

merge an empty <a> with text in a <span>

I have an empty anchor, and a span that has the text of the URL in it.  I need to merge the <span> and the empty anchor into a link.  I've set up a demo page that shows the code I have, and the end result I need to get to.  Is this possible?  IF so, can someone please lend me a hand?

Example page is here: http://bit.ly/urlfromspan

Thank you in advance!
