Java HTML/XML - 如何使用JDOM访问XML中的值

import org.jdom.Document;
import org.jdom.input.SAXBuilder;

public class Test {

    public static void main(String[] args) throws Exception{
        SAXBuilder builder = new SAXBuilder();
        Document doc = builder.build("test.xml");
        String id1 = doc.getRootElement().getChild("values").getChild("factor").getChild("id1").getValue();
        System.out.println(id1);
        String id2 = doc.getRootElement().getChild("values").getChild("factor").getChild("id2").getValue();
        System.out.println(id2);
    }

}
