found it!

(?i)MediaBox\[\d\s\d\s\d+\s\d+\]

Hi: warrenlyle;

This is basically the same solution I gave you yesterday but will match any number of digits for the four sets of numbers.

using System.Text.RegularExpressions;
using System.IO;

            String pattern = @"(?i)MediaBox\[\d+\s+\d+\s+\d+\s+\d+\]";
            String fileName = @"C:\Temp\TestData.txt";
            StreamReader sr = new StreamReader(fileName);
            String input = sr.ReadToEnd();
            sr.Close();
            MatchCollection mc = Regex.Matches(input, pattern);
            foreach (Match m in mc)
            {
                Console.WriteLine(m.Value);
            }

Using a string formatted in the following way MediaBox[A B C D]

Your pattern, "(?i)MediaBox\[\d\s\d\s\d+\s\d+\]", will match the following

MediaBox[ followed by, "A single digit", "A single space", "A single digit", "A single space", "One or more digits","A single space","One or more digits" followed by ].
