Android XML Parsing error: Only one root element allowed

I want to parse an XML. I am posting my XML response below. In the pre tag I am getting a JSON which i want to print but I am not able to parse with my code. I am posting my code to parse this XML.

private void xmlParsing(String qrCode) {
        try {
            qrCode = qrCode.replaceAll("[^\\x20-\\x7e]", "");
            //loge("qrCode : " + qrCode);
            DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
            DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
            Document doc = dBuilder.parse(new ByteArrayInputStream(qrCode.getBytes("utf-8")));

            Element element = doc.getDocumentElement();
            element.normalize();

            NodeList nList = doc.getElementsByTagName("head");
            loge("--df--nList.getLength()---"+nList.getLength());
            for (int i=0; i<nList.getLength(); i++) {

                Node node = nList.item(i);
                if (node.getNodeType() == Node.ELEMENT_NODE) {
                    Element element2 = (Element) node;

                }
            }

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

Well, as the error said, XML only allows a single root element. You could create a fake one around the string you recieve:

qrCode = "<html>" + qrCode + "</html>";
