html parsing problem using C#

From here, I am trying to get data from stock quote for every 10 mins interval.

I used WebClient for downloading the page content and for parsing I used regular expressions. It is working fine for other urls. For the Particular URL, my parsing code not working.

I think it is the problem with javascript, When I load the page in Browser, after loading the page content, It took some extra time to plot the data. May be this guy is using some client side script for this page. Can anyone help me Please..........

as per @Vinko Vrsalovic answer, Html Agility pack is your friend. Here is a sample

  WebClient client = new WebClient();
  string source = client.DownloadString(url);

  HtmlAgilityPack.HtmlDocument document = new HtmlAgilityPack.HtmlDocument();
  document.LoadHtml(source);

  HtmlNodeCollection nodes = document.DocumentNode.SelectNodes("//*[@href]");

   foreach (HtmlNode node in nodes)
   {
    if (node.Attributes.Contains("class"))
    {
     if (node.Attributes["class"].Value.Contains("StockData"))
     {// Here is our info }
    }
   }

HTML Agility Pack will save you tons of headaches. Try it instead of using regexps to parse HTML.

For what it's worth, in the page you link to the quote data is indeed in Javascript code, check http://www.nseindia.com/js/getquotedata.js and http://www.nseindia.com/js/quote_data.js
