The problem you are having is related to the Same Origin Policy(SOP) within the browser. It basically says that code can only load data from the server it is loaded from. That is why I suggested the server side proxy in both solutions above. Unfortunately this means the server is making the request for you, so any personalized RSS feeds or ones that require authentication will not be accessible. If you would like to avoid writing your own proxy you can try using YQL for JSONP:
