Hi

I am trying to merge several jdom documents together:

      org.jdom.Element myRootElement = new org.jdom.Element("MasterDocument");
      //toplevel xml element
      org.jdom.Document myDocument = new org.jdom.Document(myRootElement);
      //get the document to be merged in
      Document myDocument = childDocument.toDom();
      //add child document record element to document root
      myRootElement.addContent(myDocument.getRootElement());


When run this gives the following error:

Exception in thread "main" org.jdom.IllegalAddException: The element
"ChildDocument" could not be added as a child of "MasterDocument":
The element already has an existing parent (the document root)
        at org.jdom.Element.addContent(Element.java:1172)


How do I incorporate the root element (and its children) from one document as
the child element of another document?

Thanks in advance.
