Question

Will be [0-9]{2}\.[0-9]{2}\.[0-9]{4}

[0-9]stands for any integer in range 0 to 9, the number in curly brackets ({2} in this case) indicates how many times should the pattern be repeated.
You need to escape the dots with a backslash because otherwise they will be interpreted as any character.
