dom4j解析xml

待解析的字符串：

第一步：引用jar包：

<!-- https://mvnrepository.com/artifact/org.dom4j/dom4j -->
<dependency>
    <groupId>org.dom4j</groupId>
    <artifactId>dom4j</artifactId>
    <version>2.1.3</version>
</dependency>

第二步：定义转换对象：

package com.rongyi.platform.game.web.controller;

import lombok.Data;

import java.io.Serializable;

/**
 * @desc:
 * @author: 毛会懂
 **/
@Data
public class CodeVO implements Serializable {
    private String Company;

    private String name;

    private String phone;
}

第三步：转换代码

package com.rongyi.platform.game.web.controller;

import com.alibaba.fastjson.JSONArray;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
