Java使用DOM解析XML文件

代码就是王道,不解释

import java.io.IOException;
import java.io.InputStream;
import java.net.DatagramPacket;
import java.net.InetAddress;
import java.net.MulticastSocket;
import java.net.URL;
import java.net.URLConnection;
import java.util.Scanner;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;


public class Test{
	
	
	
	public static void main(String[] args) {
		
		try {
			URL url=new URL("http://dota.uuu9.com/rss.xml");
			URLConnection con=url.openConnection();
			InputStream is=con.getInputStream();
			DocumentBuilderFactory factory=DocumentBuilderFactory.newInstance();
			DocumentBuilder builder=factory.newDocumentBuilder();
			Document doc=builder.parse(is);
			Element root=doc.getDocumentElement();
			NodeList nodes=root.getElementsByTagName("item");
			for(int i=0;i<nodes.getLength();i++)
			{
				Element item=(Element) nodes.item(i);
				NodeList child=item.getChildNodes();
				for(int j=0;j<child.getLength();j++)
				{
					Node e=child.item(j);
					
				if(e.getNodeType()==Node.ELEMENT_NODE)
					{
						if("title".equals(e.getNodeName()))
						{
							System.out.println(e.getFirstChild().getNodeValue());
						}
						if("link".equals(e.getNodeName()))
						{
							System.out.println(e.getFirstChild().getNodeValue());
						}
						if("description".equals(e.getNodeName()))
						{
							System.out.println(e.getFirstChild().getNodeValue());
						}
						if("pubDate".equals(e.getNodeName()))

					}
					
				}
			}
			
			
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
