// The following short XML file called "mammals.xml" is parsed 
// in the code below. It must be in the project's "data" folder.
//
// <?xml version="1.0"?>
// <mammals>
//   <animal id="0" species="Capra hircus">Goat</animal>
//   <animal id="1" species="Panthera pardus">Leopard</animal>
//   <animal id="2" species="Equus zebra">Zebra</animal>

XML xml;

void setup() {
  xml = loadXML("mammals.xml");
  XML firstChild = xml.getChild("animal");
  println(firstChild.getString("species"));
  firstChild.setString("species", "Jamides zebra");
  println(firstChild.getString("species"));
