正好是我需要的，谢谢 shaokun305(混口饭吃！)
不过，Jdom 写出来的XML文件，怎么没有换行呢？

我调试过了 ! 你的应用程序可以运行的!
但是 我想知道怎么用jsp 直接对xml 进行修改! 而且你的方法没有修改数据的功能! 除非先 del 然后再 add 那样做可太费事了!!
另外 应用程序不同于web端程序 , 我们对安全级别要求的比较高!! 你在客户端 可以随便操作xml 的配置文件么????
希望你帮我看看.......!!
为了表示感谢 上面的分都给你吧! ^_^

先下载jdom包。加入环境变量：
然后看程序：
package jdomstury;

outp.output(doc, new FileOutputStream("F:\\exampleB.xml"));

catch (JDOMException ex) {

}
再把那个例子的exampleA.xml给你：

好了，运行你的程序吧。注意：1.包的位置，2.你的目标文件xampleA.xml的路径。
然后看程序：
