        //开始解析
        try {
            Document doc = DocumentHelper.parseText(str);
            // 指向根节点<msg>
            Element root = doc.getRootElement();       
            //获取<body>标签里面的<khyh>标签的值
            Element mark=root.element("body").element("khyh");
            //获取xml的节点内容
            String text = mark.getTextTrim();
            System.out.println(text);
