Answer 2

//仅供参考
            String str = @"*********
                        target=""countsmain"">
                        2009058 </a>
                        *********";            Regex objRegex = new Regex(@"(?im)target=""countsmain"">\s*(\d+)\s*<\/a>");            MatchCollection objMatches = objRegex.Matches(str);            Response.Write("Result :<br />");            Int32 index = 0;            foreach (Match objMatch in objMatches)
            {
                Response.Write(String.Format("{0} : {1}<br />", ++index, objMatch.Result("$1")));
            }
