Jdom 生成和解析XML字符串

//生成XML字符串

package com.abin.xml;

import java.io.ByteArrayOutputStream;

import org.jdom.Document;
import org.jdom.Element;
import org.jdom.output.XMLOutputter;

public class CreateXML {

 public static String Create(){
  Element root=new Element("people");
  Document doc=new Document(root);

  for(int i=0;i<5;i++){

   element.setAttribute("id", ""+""+i);

   element.addContent(new Element("name").setText("abin"+i));

 }

//解析XML字符串

package com.abin.xml;

import java.io.StringReader;
import java.util.List;

import org.jdom.Document;
import org.jdom.Element;
import org.jdom.input.SAXBuilder;
import org.xml.sax.InputSource;

public class ParseXML {

 public static void Parse(String xml){
  //创建一个新的字符串
  StringReader reader=new StringReader(xml);
  InputSource source=new InputSource(reader);
  SAXBuilder sax=new SAXBuilder();

  try {
   Document doc=sax.build(source);
   Element root=doc.getRootElement();
   System.out.println("root's name="+root.getName());
   System.out.println("root's value="+root.getValue());

   List node=root.getChildren();
   Element el=null;
   for(int i=0;i<node.size();i++){
    el=(Element)node.get(i);
    System.out.println("el's name="+el.getName());
    System.out.println("el's value="+el.getValue());
    List node1=el.getChildren();
    Element el1=null;
    for(int j=0;j<node1.size();j++){
     el1=(Element)node1.get(j);
     System.out.println("el1's name="+el1.getName());
     System.out.println("el1's value="+el1.getValue());
    }
   }

  } catch (Exception e) {
   e.printStackTrace();
  }

 }

//Junit测试XML

package com.abin.xml;

import org.junit.Before;
import org.junit.Test;

public class UseXML {
 CreateXML create=null;
 ParseXML parse=null;

 @Before
 public void setUp(){
  create=new CreateXML();
  parse=new ParseXML();
 }

 @Test
 public void test(){
  String result=create.Create();
  System.out.println("生成的XML字符串是："+result);
  parse.Parse(result);
 }


}
