I'm making an app that gets most of it's information from an XML file. I have been using an RSS-like XML, but now I've found an XML with much more information that I want to use. I already have the XML reader working, but when I put the XML into my code, it returns with "NO DATA", which is what I told it to do if it can't get any data from the XML. I've tried to find ways to make the app only read the part of the XML, but I haven't found a way that works yet.

This is the XML I am trying to read.
