使用JDom操作XML

package jdom;

import java.io.File;
import java.io.IOException;

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

public class JDomConvert ...{


    public static void main(String[] args) ...{
        SAXBuilder builder=new SAXBuilder();
        String realpath=System.getProperty("user.dir")+File.separator+"src"+File.separator+"jdom"+File.separator+"student.xml";
        try ...{
            //新增节点
            Document doc=builder.build(new File(realpath));
            Element eleStu=new Element("student");
            Element eleName=new Element("name");
            Element eleAge=new Element("age");
            
            eleName.setText("gao1");
            eleAge.setText("271");
            
            eleStu.setAttribute("sn1","011");
            
            eleStu.addContent(eleName);
            eleStu.addContent(eleAge);
            
            Element root=doc.getRootElement();
            root.addContent(eleStu);
            
            //删除节点
            root.removeChild("student");//删除第一个student
            
            //修改节点
            root.getChild("student").getChild("age").setText("22");//得到第一个student的age,并修改为22
            
            
        } catch (JDOMException e) ...{
            e.printStackTrace();
        } catch (IOException e) ...{
            e.printStackTrace();
        }

    }
