And there's also XPath iterators to get the text nodes...

function rot13tree(doc)
{
  var iterator = new XPathEvaluator();
  var path = iterator.evaluate("//text()", doc, null, 
XPathResult.ORDERED_NODE_ITERATOR_TYPE, null);
  while (var node = path.iterateNext()) {
    var data = rot13(node.data);
    if (data != node.data)
      node.replaceData(0, data.length, data); // node.data = data
  }
}
