JAVA CODE

dbf = DocumentBuilderFactory.newInstance();
            db = dbf.newDocumentBuilder();

            is = new InputSource();
            is.setCharacterStream(new StringReader(respString));
            doc = db.parse(is);
            nodes = doc.getElementsByTagName("soapenv:Envelope");
            for (int i = 0; i < nodes.getLength(); i++) {
                Element element = (Element) nodes.item(i);



                NodeList txnStatus = element.getElementsByTagName("returnCode");
                Element line = (Element) txnStatus.item(0);
                bean.setTxnStatus(getCharacterDataFromElement(line));



                NodeList message = element.getElementsByTagName("returnMsg");
                line = (Element) message.item(0);
                bean.setMessage(getCharacterDataFromElement(line));
            }
