目的是要读出 tasklist 下面每个 task 的名字：
sub1
sub2
sub3
...

package xml;

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

public class ProjectParser {
    public static void main(String args[]) throws Exception{
        DocumentBuilderFactory factory=DocumentBuilderFactory.newInstance();
        DocumentBuilder builder=factory.newDocumentBuilder();
        Document doc=builder.parse(new File("3.xml"));
        NodeList list=doc.getElementsByTagName("task");
        for(int i=0;i<list.getLength();i++){
            Element task=(Element)list.item(i);
            NodeList names=task.getElementsByTagName("name");

            System.out.println(text.getNodeValue());
