XML

XML is a representation of an XML object, able to parse XML code. Use loadXML() to load external XML files and create XML objects.

Only files encoded as UTF-8 (or plain ASCII) are parsed properly; the encoding parameter inside XML files is ignored.

• // 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
