Answer 2

            string str = @"<div align='center'  style='cursor:hand' onclick=' openContent(262962);'>123 </div>
<div align='center'  style='cursor:hand' onclick=' openContent(262963);'>124 </div> ";
            Regex reg = new Regex(@"(?is)openContent\((.*?)\)");            MatchCollection mc = reg.Matches(str);
           
           
            foreach (Match m in mc)
            {
                Console.WriteLine(m.Groups[1].ToString());
