File f=new File("E:\\music.xml");
	
	DocumentBuilderFactory factory=DocumentBuilderFactory.newInstance();
	
	DocumentBuilder builder=factory.newDocumentBuilder();
	
	Document doc = builder.parse(f);

	
	NodeList nl = doc.getElementsByTagName("music");//获得名称为music的标签
	for (int i=0;i<nl.getLength();i++){
	System.out.print("歌曲名称" + doc.getElementsByTagName("name").item(i).getFirstChild().getNodeValue());
	System.out.print("歌曲大小:" + doc.getElementsByTagName("size").item(i).getFirstChild().getNodeValue());}
