You can copy the content of one DOMDocument object to another with the save() method. Call the source DOMDocument's save method with the other object as a parameter. The following function defines two DOMDocument objects, xmldoc and xmldoc2. We first read the external mydvd.xml file into xmldoc, and then copy its content to the xmldoc2 object:

<SCRIPT LANGUAGE="JavaScript">
<!--
function load() {
  var xmldoc;
  xmldoc = new ActiveXObject("Msxml2.DOMDocument.3.0");
  xmldoc2 = new ActiveXObject("Msxml2.DOMDocument.3.0");
  xmldoc.async = false;
  xmldoc.load("mydvd.xml");
  xmldoc.save(xmldoc2);
  alert(xmldoc2.xml);
}
// -->
</SCRIPT>
Let's call this script now. The alert box shows the content of xmldoc2.
