 // Adds up the values listed in a sample XML document and adds a new element with the total.
 var xml = '<things>'
     + '<plates>12</plates>'
     + '<bowls>18</bowls>'
     + '<cups>25</cups>'
     + '</things>';
 var document = XmlService.parse(xml);
 var root = document.getRootElement();
 var items = root.getChildren();
 var total = 0;
 for (var i = 0; i < items.length; i++) {
   total += Number(items[i].getText());
 }
 var totalElement = XmlService.createElement('total').setText(total);
 root.addContent(totalElement);
