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();
}
}
}
