//创建根节点
Element rootElement = DocumentHelper.createElement("student");
rootElement.addAttribute("sno", "20160810001");
//创建子节点
Element unameElement = DocumentHelper.createElement("uname");
unameElement.setText("张三");
Element pwdElement = DocumentHelper.createElement("pwd");
pwdElement.setText("123456");

rootElement.add(unameElement);
rootElement.add(pwdElement);
//创建一个文档
Document document = DocumentHelper.createDocument(rootElement);

//写出到硬盘
