In the weather widget we need to be able to parse the Xml that is returned from the yahoo weather api. Unfortunately we cannot use jQuery and do not readily have access to the DOM through our DomHelper module. This complicates things tremendously. Eric S. mentioned the possibility of using an XmlHttpRequest in a worker to get around it, but I would rather find a cleaner way. I'm going to be experimenting with this and chrome url for the next day or two.
