Match match = Regex.Match(x, "(?<=(<p[.\\s\\S]*?>))[.\\s\\S]*?(?=(</p>))", RegexOptions.Multiline | RegexOptions.Singleline);
            MatchCollection m=Regex.Matches(x, "(?<=<p[.\\s\\S]*?>)[.\\s\\S]*?(?=</p>)", RegexOptions.Multiline | RegexOptions.Singleline);
            while (match.Success)

                        tem_description = Regex.Replace(tem_description, "&[^;]+;", "");
