            e.printStackTrace();
        }
        
        
    }
}

运行结果：

主要的代码：

Document doc = DocumentHelper.createDocument();

Element root = doc.addRootElement("list");

for(Student stu : list){
Element ele = root.addElement("student");
ele.addElement("name").addText(stu.getName());
ele.addElement("age").addText(stu.getAge());
ele.addElement("school").addText(stu.getScholl());
ele.addElement("score").addText(stu.getScore());
}
XMLWriter writer = new XMLWriter(new FileOutputStream("stu.xml"));
writer.write(doc);
writer.close();
