I'm trying to write a piece of code in golang which takes an xml and Unmarshall it. I'm pretty sure that I've done something wrong at the end of my structure but I can't figure out what. So I would appreciate if someone can help me by telling why the printed rate doesn't have any value, and how I could fix this issue. Thanks a lot!
