Loading xml mixed data in C# for an editor

I am building a world editor for a game and I need help with the process of loading a map saved from the editor. Everything is complete except for the map loading. I haven't been able to find a description online on how to load mixed data from an xml file (as in integers & strings). I can't mess with the output format because I don't have access to change the game client's method of  parsing the xml, I just know that it works with this format.  I know how to load xml in c++ using tinyxml but my c# is really rusty. I just need to know how to take data from each of the elements so I can use them in the world editor. Any help would be massively appreciated.
