Get nested xml document in DOm java

What am i trying to do? - I am trying to extract the InputData document in below xml as XML(not as textContent of elements).

<?xml version="1.0" encoding="UTF-8"?>
<Test>
     <Identifier>1</Identifier>
     <Mode>SYNCHRONOUS</Mode>
     <Callback>null</Callback>
     <InputData>
               <iid>
                   <test3>p</test3>
                   <test4>p1</test4>
              </iid>
     </InputData>
</Test>

When i do node.item(i).textContent(), I want output as :

          <iid>
               <test3>p</test3>
               <test4>p1</test4>
          </iid>

What is the problem Code? -

 private void doProcessing(Document xmldoc) {

            Element rootEliment = xmldoc.getDocumentElement();
            // System.out.println("NodeName : "+rootEliment.getNodeName());
            NodeList children = rootEliment.getChildNodes();
            NamedNodeMap nnl = rootEliment.getAttributes();

            Node inputdata = nnl.getNamedItem("InputData");
            // inputdata.getOwnerDocument().g
            // System.out.println("inputDataValuefirst: "+inputdata.getTextContent());
            // NodeList testList = xmldoc.getElementsByTagName("InputData");
            for (int i = 0; i < children.getLength(); i++) {
                // Element el = (Element)children.item(i);
                //System.out.println("NodeName: " + children.item(i).getNodeName()
                    //  + " TextValue: " + children.item(i).getTextContent());
                if (children.item(i).getNodeName() == "InputData") {
                    NodeList childs = children.item(i).getChildNodes();
                    for (int j = 0; j < childs.getLength(); j++) {
                        System.out.println("NodeVal;ue: "
                                + childs.item(j).getNodeName() + " Text: "
                                + childs.item(j).getTextContent());
                    }

                }
            }
        }

gives me: NodeVal;ue: iid Text: pp1

I have also tried various other combinations. All of them give the textContent of child nodes but not the node itself. How can i achieve this?
