解析XML的两种方法

一、用SAXReader 方式解析:实例测试类TestXML

package *

import java.io.ByteArrayInputStream;
import java.util.Iterator;

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

public class TestXml {

/**
* @param args
*/
public static void main(String[] args) {
try {
   // TODO Auto-generated method stub
   //定义要解析的XML字符串
   String transMessage = "<?xml version=/"1.0/" encoding=/"GBK/"?><message>"
     + "<body>"
     + "<ticketNotify>"
     + "<ticket id=/"6000012007051000000231/" dealTime=/"20070510165423/" status=/"0000/" message=/"成功,系统处理正常/"/>"
     + "<ticket id=/"6000012007051000000232/" dealTime=/"20070510165424/" status=/"2012/" message=/"禁止倍投/"/>"
     + "</ticketNotify>" + "</body></message>";
   // 创建xml解析对象
   SAXReader reader = new SAXReader();
   // 定义一个文档
   Document document = null;
   //将字符串转换为
   document = reader.read(new ByteArrayInputStream(transMessage
     .getBytes("GBK")));
   // 得到xml的根节点(message)
   Element root = document.getRootElement();
   //定义子循环体的变量
   Element ticket=null;

   Iterator tickets = null;
   for (tickets = root.element("body").element("ticketNotify").elementIterator(); tickets.hasNext();) {
    ticket = (Element) tickets.next();
    System.out.print(ticket.attributeValue("id")+" ");
    System.out.print(ticket.attributeValue("dealTime")+" ");
    System.out.println(ticket.attributeValue("status"));



   }
   //Element.asXML方法，获得包括该标签的所有XML数据
   System.out.println(root.element("body").asXML());



} catch (Exception e) {
   e.printStackTrace();
}
}

}

二、DocumentHelper 方式解析:实例测试类TestXML

package *;

import java.io.ByteArrayInputStream;
import java.util.Iterator;

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

public class TestXml {

/**
* @param args
*/
public static void main(String[] args) {
try {
   // TODO Auto-generated method stub
   //定义要解析的XML字符串
   String transMessage = "<?xml version=/"1.0/" encoding=/"GBK/"?><message>"
     + "<body>"
     + "<ticketNotify>"
     + "<ticket id=/"6000012007051000000231/" dealTime=/"20070510165423/" status=/"0000/" message=/"成功,系统处理正常/"/>"
     + "<ticket id=/"6000012007051000000232/" dealTime=/"20070510165424/" status=/"2012/" message=/"禁止倍投/"/>"
     + "</ticketNotify>" + "</body></message>";
   // 创建xml解析对象
//   SAXReader reader = new SAXReader();
   // 定义一个文档
   Document document = null;
   //将字符串转换为
//   document = reader.read(new ByteArrayInputStream(transMessage
//     .getBytes("GBK")));

   document = DocumentHelper.parseText(transMessage);
   // 得到xml的根节点(message)
   Element root = document.getRootElement();
   //定义子循环体的变量
   Element ticket=null;

   Iterator tickets = null;
   for (tickets = root.element("body").element("ticketNotify").elementIterator(); tickets.hasNext();) {
    ticket = (Element) tickets.next();
    System.out.print(ticket.attributeValue("id")+" ");
    System.out.print(ticket.attributeValue("dealTime")+" ");
    System.out.println(ticket.attributeValue("status"));



   }
   //Element.asXML方法，获得包括该标签的所有XML数据
   System.out.println(root.element("body").asXML());



} catch (Exception e) {
   e.printStackTrace();
}
}

}
