C# regex to match a number in fourth line

Question

I'm new to C# regex. I haven't been able to match the number in the fourth line (including a blank line on third line) using C# regex:

 <th>Total Members</th>
 <td>

    87
 </td>

Answer 1

Match match = Regex.Match(input, @"<th>Total Members</th>\s*<td>\s*(\d+)\s*</td>", RegexOptions.Multiline);
if (match.Success)
{
    Console.WriteLine(match.Groups[1].Value);
}

Answer 2

尝试使用这个正则表达式

^[0-9]{2}$

Answer 3

It seems that your are going to parse html with regex.

I think you should use HTML Agility Pack instead.
