已经把html格式的文件显示在JEditorPane，但怎样可以得到这个html文件里面的一个文本框的值

但这个文本框里的值是在显示了这个html文件后才输进去的，不是本来就有的，就是说：在JEditorPane里显示了html文件后，用户在一个文本框里填写了东西，我可以得到他填写的东西吗？/

如果可以，以后就不用做界面了。
一个 JEditorPane + HTML 然后 …… 哈哈
HTMLDocument doc = (HTMLDocument)pane.getDocument();
HTMLDocument中有如下方法：
public Element getElement(String id)；
自己看看文档吧！哈哈！

有意思
to:lucumu(沸腾的咖啡) 什么意思！？
to:pengji(彭乃超)，谢谢你的回答，你的方法我之前已经试过了，像<input id="a">的html我最多只能get到input这个字符窜，而input框里的值我怎么也get不到，你能告诉我到底能不能get到吗？你试过吗？
