我想解析一个简单的网站，并从该网站中抓取信息。

我曾经用DocumentBuilderFactory解析XML文件，但我尝试对html文件做同样的事情，但是它总是陷入无限循环。

    URL url = new URL("http://www.deneme.com");
    URLConnection uc = url.openConnection();

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

     FileWriter outFile = new FileWriter("orhancan");
     PrintWriter out = new PrintWriter(outFile);

    while ((inputLine = in.readLine()) != null) {
        out.println(inputLine);
    }

    in.close();
    out.close();

    File fXmlFile = new File("orhancan");
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
    Document doc = dBuilder.parse(fXmlFile);


    NodeList prelist = doc.getElementsByTagName("body");
    System.out.println(prelist.getLength());

有什么问题吗？还是有任何更简单的方法可以从网站中获取给定html标签的数据？
