SAXParser to parse XML data from CLOB in Java-Hibernate

I'm working on a web application that uses Spring MVC and Hibernate,

I want to parse a XML data from CLOB and print it, I was follow this tutorial thinktibits and mkyong but I got stuck from this point, I can't print the xml element that I want,

this is my code,

@RequestMapping(value="/admin/Detail-BPJS-TK.html")
public ModelAndView listDetailBPJSTK(ModelMap model, HttpServletRequest request, HttpServletResponse response)throws ParserConfigurationException, SAXException, Exception{
    if(!((request.getParameter("MESSAGEID")) == null)){
        String MESSAGEID = request.getParameter("MESSAGEID");
        System.out.println(MESSAGEID);
        //140721438362
        //DetailBPJS detailbpjs = detailbpjsService.get(MESSAGEID);

        //String tes = detailbpjs.getMESSAGEID();
        //System.out.println(tes);

        Configuration cfg = new Configuration();
        cfg.configure("hibernatesoaappbpjstk.cfg.xml");

        SessionFactory factory = cfg.buildSessionFactory();
        Session session = factory.openSession();

        String pay = "PAYMENT";
        String sub = "PROCESSED";

        Query query = session.createQuery("from DetailBPJS where TRANSACTION = :tra and SUBTRANSACTION = :sub and MESSAGEID = :mes");
        query.setParameter("tra", pay);
        query.setParameter("sub", sub);
        query.setParameter("mes", MESSAGEID);

        @SuppressWarnings("unchecked")
        List <DetailBPJS> result = query.list();

        if(result.isEmpty()){
            System.out.println("Please, check the 'No. Billing' again!!");
            System.out.println(MESSAGEID);
            model.addAttribute("errorMessageBPJSTK", "true");
        }else{
            DetailBPJS data = (DetailBPJS)result.get(0);
            String nom1 = data.getTRANSACTION();
            String nom2 = data.getSUBTRANSACTION();
            String nom3 = data.getUUID();
            Clob nom4 = data.getRAWDATA();

            System.out.println(nom1 + " - " + nom2 + " - " + nom3 + " - " + nom4);
            //140721438362

            //convert clob to java.io.reader
            Reader myclob = nom4.getCharacterStream();

            //create InputSource from Reader
            InputSource myinput = new InputSource(myclob);

            try {

                SAXParserFactory factoryz = SAXParserFactory.newInstance();
                SAXParser saxParser = factoryz.newSAXParser();
