使用jdom读取xml问题

[wanding_]

java文件和test.xml在同一个包下面
package com.yl.readxml;
import java.io.File;
import java.io.FileInputStream;
import java.util.List;

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

public class readxml2 {
public static void main(String[] args) throws Exception{
SAXBuilder sb=new SAXBuilder();
String name="test.xml";
Document doc=sb.build(readxml2.class.getClassLoader().getResourceAsStream("test.xml"));
Element root=doc.getRootElement(); //HD
List list=root.getChildren("person"); //child
for(int i=0;i<list.size();i++)
{
Element element=(Element) list.get(i);
String id=element.getAttributeValue("id");
System.out.println(element.getAttributeValue("name")+" "+element.getAttributeValue("email"));
}
}

}

test.xml如下
<?xml version="1.0" encoding="UTF-8"?>
<addressbook>
<person id="1">
<name>王奇鹏</name>
<email>[e-mail]</email>
</person>
<person id="2">
<name>王艳明</name>
<email>[e-mail]</email>
</person>
<person id="3">
<name>王广庆</name>
<email>[e-mail]</email>
</person>
</addressbook>
