下面是用于存储元素的类
- package com.fenuang.demo4j;
- import org.omg.Messaging.SyncScopeHelper;
- public class contest {
- private String id;
- private String name;
- private String email;
- private String qq;
- private String wife;
- /**
- * @param id
- * @param name
- * @param email
- * @param qq
- * @param wife
- */
- public contest(String id, String name, String email, String qq, String wife) {
- super();
- this.id = id;
- this.name = name;
- this.email = email;
- this.qq = qq;
- this.wife = wife;
- }
- /**
- * @param id
- * @param name
- * @param email
- * @param qq
- * @param wife
- */
- public contest() {
- }
- public String getId() {
- return id;
- }
- public void setId(String id) {
- this.id = id;
- }
- public String getName() {
- return name;
- }
- public void setName(String name) {
- this.name = name;
- }
- public String getEmail() {
- return email;
- }
- public void setEmail(String email) {
- this.email = email;
- }
- public String getQq() {
- return qq;
- }
- public void setQq(String qq) {
- this.qq = qq;
- }
- public String getWife() {
- return wife;
- }
- public void setWife(String wife) {
- this.wife = wife;
- }
- @Override
- public String toString() {
- // TODO Auto-generated method stub
- return this.email + "--" + this.id + "--" + this.name + "--" + this.qq + "--" + this.wife+" ";
- }
- }
下面是要被读取的xml文件
- <?xml version="1.0" encoding="utf-8"?>
- <contestList>
- <user id="001">
- <name>王五</name>
- <email>2222222</email>
- <qq>4fenuang</qq>
- <wife>6fenuang</wife>
- </user>
- <user id="002">
- <name>李四</name>
- <email>4444444</email>
- <qq>4fenuang</qq>
- <wife>6fenuang</wife>
- </user>
- <user id="003">
- <name>张三</name>
- <email>2fenuang</email>
- <qq>333333</qq>
- <wife>6fenuang</wife>
- </user>
- </contestList>
