    Hi,

    Do you mean that the server response is html? You could you use a regular expression.

    If you have control over the server have it return json. That is the most efficient data transfer format.

    Parsing an HTML page using an XML parser is going to be problematic. I would suggest you look into the documentation on Yahoo! Pipes (http://pipes.yahoo.com) and use it to parse the page and return back the URL in a JSON packet to your widget. I apologize, I can't offer much help on how to do that in Pipes, but I know it's possible and hopefully the docs will have a good example.
