提取搜索结果

Question

我是java编程的新手。我正在编写一个程序/应用程序，用一个用户给出的关键字一次查询yahoo，bing和hotbot。我想在一个页面中完全显示结果URL。但我只能发送查询并将生成的html代码保存在记事本文件中。 html文档中有很多垃圾和广告。如何从搜索结果中仅获取生成的URL并显示它们？

我做了这么多：

       BufferedReader in = new BufferedReader(new InputStreamReader(
                            connect.getInputStream()));
       String inputLine;

       while ((inputLine = in.readLine()) != null) 
       {

           System.out.println(inputLine);
           in.close();
       }

       new InputStreamReader(url.openStream()));
