Regex in c#

[Nightcrawler]

I am building a web page where people can link in a youtube video by
copying and pasting the link that is provided by youtube. How can I
use a regular expression to capture the URL only from the link below:

<object width="425" height="355"><p aram name="movie" value="http://
www.youtube.com/v/xSqNx7vJLDE&rel =1"></param><param name="wmode"
value="transpar ent"></param><embed src="http://www.youtube.com/v/
xSqNx7vJLDE&rel =1" type="applicati on/x-shockwave-flash"
wmode="transpar ent" width="425" height="355"></embed></object>

Thanks

Regex r = new Regex ("src=\"(?<YouT ube>http://www\\.youtube\\ .com\\S*)\"");
Match s = r.Match("<objec t width=\"425\" height=\"355\"> <param name=\"movie\"
value=\"http://www.youtube.com/v/xSqNx7vJLDE&rel =1\"></param><param name=\"wmode\"v alue=\"transpar ent\"></param><embed
src=\"http://www.youtube.com/v/xSqNx7vJLDE&rel =1\" type=\"applicat ion/x-shockwave-flash\"wmode=\" transparent\" width=\"425\"
height=\"355\"> </embed></object>");

Console.Write(s .Groups["YouTube"]);

Watch out for unintended line-breaks.

Brian,

Thanks! How do I use this in a regularexpressi on validator in my aspx
file. There is a problem using quotation marks within the
ValidationExpre ssion="" property.

Thanks

Write them as &quot; I guess... Or set the value through the designer.
