Cross-site XML access using javascript without server access

I asked a question earlier but did not word it correctly so it got brushed over.

Basically, I am creating a windows 7 gadget that will access XML data from www.weather.gov and display some current conditions. 

        function weat()
        {

            var url = "http://www.weather.gov/xml/current_obs/KMSY.xml";


            source.open("GET", url, false);
            source.send(null);
            info = source.responseXML;

            document.write("<table border='1'>");
            var stuff = info.getElementsByTagName("temp_f");

            document.write("<tr><td>");
            document.write(stuff);
            document.write("</tr></td>");
            document.write("</table>");

        }

Basically I am trying to get this to work from my desktop, and I'm not totally sure what the problem is. I still think it is a cross-site problem, since stuff prints as undefined, but I'm not totally sure of that. If anyone could help me, I've been googling possible solutions for about 6 hours now and I'm getting pretty frustrated.

You either need a server-side proxy or you need to find a weather service that supports JSONP

I'm not familiar with Gadget. But in desktop browsers, I'm afraid Same origin policy prevent from any cross domain access.

One exception is that in Chromium, local pages (file://) can access remote URL only if --disable-web-securities is set when starting Chromium in command line.
