Help, usage of Document::ImportNode

[John Gentilin <jo...@eyecatching.com>]

I am trying to use the importNode function on the Document object to
overlay one document on top of another one, effectively a merge. It all
seems to run find, except that the imported document is not apparent
when I serialize the destination document.  I included my example code.
The importNode works without an exception and its return value behaves
as I would expect it. (I get different results when changing the value
of deep).
I even tried to import Doc2 into a new Document, same problem.

Am I missing something here ??

What is the intended use of this method ??

TIA

      Document Doc1 = parseDoc( file1 );
      Document Doc2 = parseDoc( file2 );

      System.out.println("Start of Document 1");
      serializeDocument(Doc1);

      System.out.println("Start of Document 2");
      serializeDocument(Doc2);

      // Test Code
      // Doc1 = getNewDocument():

      Element root1 = Doc1.getDocumentElement();
      Element root2 = Doc2.getDocumentElement();

        // Works without error
      Node rNode = Doc1.importNode(root2, true);

      System.out.println("Start of Output");
       // Only has the original content of Doc1, not the result of the
merge
      serializeDocument(Doc1);

      System.out.println("Start of importNode Return Value");
       // contains what I would expect, if on import deep == false then
only the top
       // level node, if its true then the whole contents of Doc2
      serializeDocument(rNode);
