Regular expression to find src attribute value of img tag

This regex is very handy when we want to parse html tags and use them in our code

Regex reSrc = new Regex(@"src=(?:(['""])(?<src>(?:(?!\1).)*)\1|(?<src>[^\s>]+))", RegexOptions.IgnoreCase | RegexOptions.Singleline);

Match mSrc = reSrc.Match(htmlImageTag);

if (!string.IsNullOrEmpty(mSrc.Groups["src"].Value))
{
         string imageUrl = mSrc.Groups["src"].Value;
}
