摘要：dom4j解析指定模板的xml文件！


一：首先建立一个java项目


二：导入dom4j的jar，我这里导入的是dom4j-1.6.1.jar，具体请自行百度下载


三：xml模板内容，我这里是直接解析xml文件，也可以把xml文件转换为xml字符串进行解析：

<?xml version="1.0" encoding="UTF-8"?>
    <message>
      <body>
        <field-list name="RECORD" size="2">
          <field-list name="1">
            <field name="messageId">1_20170116175008968_102157946</field>
            <field name="mobilePhone">18611966723</field>
            <field name="resultCode">-10</field>
          </field-list>
          <field-list name="2">
            <field name="messageId">1_20170116175008968_102157946</field>
            <field name="mobilePhone">13521196327</field>
            <field name="resultCode">-10</field>
          </field-list>
        </field-list>
        <field name="resultCode">0</field>
        <field name="errorCode">0</field>
      </body>
    </message>


四：java代码： 

package com.wwtl.sms;

import java.io.File;
import java.util.Iterator;
import java.util.List;

import org.dom4j.Attribute;
import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

public class XmlTest {

  public static void main(String[] args) {
    //1.读取XML文件,获得document对象              
        SAXReader reader = new SAXReader();               
        try {
      Document document = reader.read(new File("E:\\smsworkspace\\WwtlSmsDemo\\src\\text.xml"));
      Element rootElement = document.getRootElement();//获取根节点
      System.out.println("根节点的名称：" + rootElement.getName());
      Iterator iter = rootElement.elementIterator("body");//获取跟节点下的子节点body
      //遍历body节点
      while(iter.hasNext()){
        Element recordEle = (Element) iter.next();
        Iterator elementIterator = recordEle.elementIterator("field-list");
        while(elementIterator.hasNext()){
          Element element = (Element) elementIterator.next();
          Iterator elementIterator2 = element.elementIterator();
          while(elementIterator2.hasNext()){
            Element element2 = (Element)elementIterator2.next();
            Iterator elementIterator3 = element2.elementIterator("field");
            while(elementIterator3.hasNext()){
              Element element3 = (Element)elementIterator3.next();
              List<Attribute> attributes = element3.attributes();
              for (Attribute attribute : attributes) {
                //String name = attribute.getName();
                String value = attribute.getValue();
                    //System.out.println("当前节点名称："+element3.getName() + " 当前节点属性名称："+name+" 当前节点属性值："+value + " 当前节点的内容："+element3.getTextTrim());
                    if(value.equals("resultCode")){
                      System.out.println("节点的内容：" + element3.getTextTrim());
                      if(element3.getTextTrim().equals("0")){
                        System.out.println("短信发送success!");
                      }else{
                        System.out.println("短信发送fail！");
                      }
                    }
              }
            }
            
          }
        }
      }
    } catch (Exception e) {
      e.printStackTrace();
    }  
  }
  
}


我这里是获取field节点下面的子节点的内容！
