It seems XNA and GSE (Game Studio Express) does not ship with a simple xml importer and/or processors, so you can use xml files as a game asset. The XMLDocContentProcessor library allows XNA developers to use regular xml files as game assets using the xna content pipeline, and returns a XMLDocument object containing the xml data using content.Load<XMLDocument>("AssetName");
