下載頁面源比呈現的頁面源

http://www.gpw.pl/akcje_i_pda_notowania_ciagle

（它的主要股市在波蘭的網站）

我我已經得到了一個用C++編寫的程序，它將網站的源文件下載到文件中。但問題是，它不包含我感興趣的東西（當然是股票的價值）。

如果您將該網站的來源與「查看元素」（RMB - >查看元素）選項進行比較，您可以看到「查看元素」確實包含了股票的值。

<td>75.6</td> 
<tr class="even red">

等等...

該網站的下載源沒有這些信息。

所以我們有2個問題

1）爲什麼該網站的源是從「視圖元素」選項有什麼不同？

2）如何轉移我的程序，以便它可以下載正確的代碼？
