使用dom4j寫xml檔案——源碼

標籤：lower   src   ati   ima   on()   tty   uid   data   輸出   

dom4j版本：2.1.1

使用dom4j產生xml文檔步驟：

1、建立一個Document對象的空白文檔。

2、向Document中添加根項目，返回的Element表示根項目，xml文檔只有一個根項目。

3、添加子項目。

4、建立XmlWriter對象

5、輸出Document對象

元素對象

 1 package cnblogs.testCSV; 2  3 public class Person { 4     private String id; 5     private String name; 6     private String sex; 7     private int age; 8  9     public Person() {10     }11 12     public Person(String id, String name, String sex, int age) {13         this.id = id;14         this.name = name;15         this.sex = sex;16         this.age = age;17     }18 19     public String getId() {20         return id;21     }22 23     public void setId(String id) {24         this.id = id;25     }26 27     public String getName() {28         return name;29     }30 31     public void setName(String name) {32         this.name = name;33     }34 35     public String getSex() {36         return sex;37     }38 39     public void setSex(String sex) {40         this.sex = sex;41     }42 43     public int getAge() {44         return age;45     }46 47     public void setAge(int age) {48         this.age = age;49     }50 }
