The method replace takes two arguments, the first being the property
name of the property or properties to be replaced, the second being the
value to replace the properties.
If there is exactly one property matching the property name passed in
then this property is replaced by the value passed in.
If there are several properties matching the property name passed in
then the first property matching the property name is replaced with the
value passed in while the other matching properties are deleted.
The method always returns the XML object it is called on.
Here are some examples:
  var gods = <gods>
    <god>Kibo</god>
    <devil>Xibo</devil>
    <god>Jaffo</god>
  </gods>;
  // replace exactly one child
  gods.replace(0, <god>Maho</god>);
  alert(gods);
  /* shows
  '<gods>
     <god>Maho</god>
     <devil>Xibo</devil>
     <god>Jaffo</god>
   </gods>'
  */
  // replace all <god> children
  gods.replace('god', <god-substitute>Maho</god-substitute>);
  alert(gods);
  /*
  '<gods>
     <god-substitute>Maho</god-substitute>
     <devil>Xibo</devil>
   </gods>'
  */
  // replace all children
  gods.replace('*', <text>Who is GOD?</text>);
  alert(gods);
  /* shows
  '<gods>
     <text>Who is GOD?</text>
   </gods>'
  */
