Java中解析XML文件（字符串）的方法-----SAXRead
用SAXReader 方式解析
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();
}
}
}
总结:
Document document=new SAXReader.reader(“xml文路径/文件名xxx.xml”);//得到Document对象
Element root = document.getRootElement()//获得根节点
Iterator iterator=root.elementIterator(); //从根节点遍历子节点
//List<Element> list = ele.elements("ele"); //获取节点循环遍历
Iterator iterator=Element.elementIterator(); //再从子节点在遍历其子节点
对节点访问其属性用：Attribute leaderAttr =Element. attribute(“xxx”);
对节点访问其某个属性leaderAttr的名称：leaderAttr.getName()；
对节点访问其某个属性leaderAttr的值：leaderAttr.getValue()
对节点访问其名称：Element.getName();
对节点访问其文本：Element. getText();
