Processing loadXML()用法及代码示例

// 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>
// </mammals>

XML xml;

void setup() {
  xml = loadXML("mammals.xml");
  XML[] children = xml.getChildren("animal");

  for (int i = 0; i < children.length; i++) {
    int id = children[i].getInt("id");
    String coloring = children[i].getString("species");
    String name = children[i].getContent();
    println(id + ", " + coloring + ", " + name);
  }
}

// Sketch prints:
// 0, Capra hircus, Goat
// 1, Panthera pardus, Leopard
// 2, Equus zebra, Zebra
