If I export some grades with the xml grade export scores will show up between the <score> and </score> tags. When I Publish the grades and get a new Public Key and click on the public link to the file, the file is missing the grades. This worked great until we just upgraded our Moodle to 2.9. I had been using a Google spreadsheet to automatically generate bar graphs from the public xml feed. The bar graphs were embedded in a Google Site so bar graphs were updating even as students finished taking for example a test. It was awesome and I was going to start trying to get Arduino to light up some LEDs also but after the upgrade I can't get this to work anymore.
