processxml.java

Java编写的DOM的XML的解析器。用 DOM 解析模型的优点是编程容易

import org.w3c.dom.*;
import javax.xml.parsers.*;

public class ProcessXML {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub

		try
		{
			DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
			
			DocumentBuilder builder = factory.newDocumentBuilder();
			
			Document doc = builder.parse("Teams.xml");
			
			doc.normalize();
			
			Element root = doc.getDocumentElement();
			
			if(doc!=null)
			{
				
				printNode(root);
				
			}
		}
		catch(Exception e)
		{
			e.printStackTrace();
		}
		
	}
	
	private static void printNode(Element element)
	{
		int k;
		
		NamedNodeMap attr;
		
		NodeList children = element.getChildNodes();
		
		attr= element.getAttributes();
		
		int r= children.getLength();

		}
