Search for something in HTML C#

Question

I have an Html page in string.

  <html> 
    .....
    <script>
        {
           http:\\\/\\\/cs513404v4.vk.me\\\/u3692175\\\/videos\\\/49a2e8d28c.720.mp4 
        }
        .....
    </script>
  </html>

There is a link in this html page. How can I search for "720.mp4" and take all this link. Thanks for the HELP.

Simple regexp will help you.

You are looking for something start with with http and ending with 720.mp4

The example code:

string strRegex = @"http.*720.mp4";
RegexOptions myRegexOptions = RegexOptions.None;
Regex myRegex = new Regex(strRegex, myRegexOptions);
string strTargetString = @"<html> " + "\n" + @"    ....." + "\n" + @"    <script>" + "\n" + @"        {" + "\n" + @"           http:\\\/\\\/cs513404v4.vk.me\\\/u3692175\\\/videos\\\/49a2e8d28c.720.mp4 " + "\n" + @"        }" + "\n" + @"        ....." + "\n" + @"    </script>" + "\n" + @"  </html>";

foreach (Match myMatch in myRegex.Matches(strTargetString))
{
  if (myMatch.Success)
  {
    // Add your code here
  }
}

What if there is some url at the top of file? – Sergey Berezovskiy Aug 19 '13 at 09:47
Relative urls like `/video/1234.mp4` ? – I4V Aug 19 '13 at 09:48
@I4V if so, we may have some `/video/1234.mp4` as a normal `TEXT`, not a url at all (neither absolute nor relative url). – King King Aug 19 '13 at 09:50
@user2660964 just mark it as answer – Piotr Stapp Aug 19 '13 at 09:51
