dom4j解析xml

待解析的字符串：

 第一步：引用jar包：

    org.dom4j
    dom4j
    2.1.3


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;

/**
 * @desc:
 * @author: 毛会懂
 **/
public class Xml3Controller {

    public static void main(String[] args) {
        String str = "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n" +
                "\n";
        List list = splitXml(str, "abc");

        System.out.print(JSONArray.toJSONString(list));
    }

    /**
     *  把元素解析为对象
     * xmlStr 要解析的xml字符串
     * @return
     */
    public static List splitXml(String xmlStr, String company) {

        List list = new ArrayList<>();
        Document document;
        try {
            document = DocumentHelper.parseText(xmlStr);
            Element root = document.getRootElement();
            //返回包含子元素的迭代器
            Iterator it = root.elementIterator();
            while(it.hasNext()) {
                CodeVO vo = new CodeVO();
                vo.setCompany(company);
                Element element = (Element) it.next();
                vo.setName(element.attributeValue("username"));
                vo.setPhone(element.attributeValue("userphone"));
                list.add(vo);
            }

        } catch (DocumentException e) {
            e.printStackTrace();
        }
        return list;
    }
}
