While XML objects have a method length this always returns 1. This is
done to intentionally blur the distinction between an XML object and an
XMLList object containing exactly one value.
Here are some examples:
  var gods = <gods>
    <god>Kibo</god>
    <god>Xibo</god>
  </gods>;
  alert(gods.length()); // shows 1
  var xmlTextNode = new XML('Kibology for all.');
  alert(xmlTextNode.length()); // shows 1
  var attributeNode = <god name="Kibo" />.@name;
  alert(attributeNode.length()); // shows 1
