This might be a very stupid question, but when I wanted to start using XML in Processing 2.0 I understand that XMLElement got changed to XML class, but how do I make it work??
I took the old example from XMLElement and tried to adapt it, without luck, what am I missing in the code below?
It gives me a NullPointerException, allthough the XMLfile sites.xml is inside the data folder.
Any ideas? Thanks!

- // The following short XML file called "sites.xml" is parsed
// in the code below. It must be in the project's "data" directory
// <?xml version="1.0"?>
// <websites>
// <site id="0" url="processing.org">Processing</site>
// <site id="1" url="mobile.processing.org">Processing Mobile</site>
// </websites>
XML xml;
void setup() {
size(200, 200);
xml = loadXML("sites.xml");
int numSites = xml.getChildCount();
for (int i = 0; i < numSites; i++) {
XML kid = xml.getChild(i);
int id = kid.getInt("id");
String url = kid.getString("url");
String site = kid.getContent();
println(id + " : " + url + " : " + site);
}
}
