I believe the Document method:
public Node importNode(Node importedNode,
                       boolean deep)
                throws DOMException
may be what you are looking for :-) You'd set "deep" to true.

Importing the nodes into the new document doesn't put them into the
document tree. You're missing a call to insert the new root into the
document. Try the following:

  Node newRoot = newDoc.importNode(doc.getDocumentElement(), true);  
  newDoc.appendChild(newRoot);

Gerv,

  I thought that might be it, but I've encountered other problems using that
method.  In particular, the code that I've used looks like:

...
Document originalDoc = parser.getDocument();
Document newDoc = null;

try  {
  DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
  DocumentBuilder db = dbf.newDocumentBuilder();
  newDoc = db.newDocument();
  newDoc.importNode(doc.getDocumentElement(), true);  
 }
catch (Exception e)  {
  e.printStackTrace();
}
 ...
NodeList nl = newDoc.getElementsByTagName("PurchaseOrder"); 	//This exists
in the original
...

When this is executed, the last line above returns nothing even though the
element exists in the original document.  Any help would be appreciated.

Thanks,
Mayer
