How do I use the method normalize?

Martin Honnen,

The method normalize takes no argument and returns the XML object it is
called on after normalizing all text content so that adjacent text nodes
are merged into one text node and empty text nodes are removed.
Note that after the initial parsing any XML object should be normalized,
only if later manipulation repeatedly inserts text it can happen that
there are adjacent text nodes so that text is not normalized.
Here is an example:
  var text = <text xml:lang="en">Initial text. Initial Text.</text>;
  alert(text.*.length()); // shows 1
  for (var i = 1; i <= 5; i++) {
    text.appendChild(new XML('Text node ' + i + '.'));
  }
  alert(text.*.length()); // shows 6;
  text.normalize();
  alert(text.*.length()); // shows 1
