I am trying to learn XML from a "Teach yourself" book. Below I have ran into a problem that is making me pull my hair out and I do not have much left. I have a HTML doc that should pull data from a external xml file in the same directory, however all I keep getting is "The root node is null" (which in the code I presume goes back to the rootelement which is set to doc1 which in turn is loading the test.xml file). I am not sure if my problem lies in the HTML, XML or script.
