SAXReader reader = new SAXReader();
    Document document = reader.read(new File(path));  
    Element vcastr = document.getRootElement();  
    Element channel = vcastr.element("channel");  
       Element item = channel.element("item");  
       Element source = item.element("source");  
       source.setText(tplName);//修改值  

       XMLWriter output = null;
             /** 格式化输出,类型IE浏览一样 */
             OutputFormat format = OutputFormat.createPrettyPrint();
             /** 指定XML字符集编码 */
             format.setEncoding("GBK");
             output = new XMLWriter(new FileOutputStream(new File(path)),format);
             output.write(document);
             output.close();
