i need to insert one node from one document (docDcont) to another document (doc) but this my code don�'t work.

  try {

            // parse the XML as a W3C Document
            DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
            Document doc = builder.parse(new File("book1.xml"));
            Document docDcont = builder.parse(new File("book.xml"));
                   

                    	   XPath xpath = XPathFactory.newInstance().newXPath();
                           String expression = "//chapter"; //select the node
                           // obtain the element as a node.
                           
                           Node node = (Node)xpath.evaluate(expression, docDcont, XPathConstants.NODE);  
                               
                           System.out.println("node name: " + node.getNodeName());
                           
                        doc.insertBefore(node, doc.getFirstChild().getNextSibling().getNextSibling());// not correct - error 
                   
        
              
            dump(doc);
