Thanks for reply. Above solution which i posted is correct.Only i need to write xml again with some transform API. Posting solution,if any body has the same problem.

try{
                            //Save the Created XML on Local Disc using Transformation APIs as Discussed
                            TransformerFactory tFactory = TransformerFactory.newInstance();
                            Transformer transformer = tFactory.newTransformer();
                            transformer.setOutputProperty(OutputKeys.INDENT, "yes");
                            Source s = new DOMSource(doc);
                            Result res = new StreamResult( new FileOutputStream(fXmlFile));
                            try {
                                transformer.transform(s, res);
                            } catch (TransformerException e) {
                                // TODO Auto-generated catch block
                                e.printStackTrace();
                            }

                        } catch(TransformerConfigurationException e)
                        {
                            e.printStackTrace();
                        }
                      } catch (Exception e) {
                        e.printStackTrace();
                      }
