创建XML文件

用java类创建一个XML文件

要生成的xml文件数据

    <students>
        <student sno="1">
            <sname>易大师</sname>
        </student>
        <student sno="2">
            <sname>德玛西亚</sname>
      </student>
    </students>

实现过程

public static void main(String[] args) throws IOException {
        List<Student> list = new ArrayList<Student>();
        list.add(new Student("易大师",1));
        list.add(new Student("德玛西亚",2));
        //创建文档对象
        Document doc = DocumentHelper.createDocument();
        //向文档中添加根元素
        Element root = doc.addElement("students");
        //遍历根元素下的学生对象
        for (Student s : list) {
            Element stuNode = root.addElement("student").addAttribute("sno", s.getSno() + "");
            stuNode.addElement("sname").setText(s.getName());
        }
        File f = new File("dom5/src/stuInfo.xml");
        System.out.println(f.getAbsolutePath());
        //准备输出流对象
        FileWriter fw = new FileWriter(f);
        //设置输出格式
        OutputFormat fmt = OutputFormat.createPrettyPrint();
        //构建xml数据输出流
        XMLWriter writer = new XMLWriter(fw,fmt);
        writer.write(doc);
        writer.flush();
        writer.close();
    }
}
