The best way to figure out exactly what has gone wrong is to open the xml file in Safari (or likely any other web browser) on your computer. It will likely tell you the exact problem, as long as a line number.
If this error occurs the game will load partially, but everything after the error will be ignored. Fortunately, in this case, it sounds like your error was on the last line, so it shouldn't have stopped anything from loading.
