Question

If I like to match all numbers which are smaller than 2000, I use the Regex

    [01]{1}[0-9]{3}

If I like to match all numbers between 1 and 5 I use the expression

    [2-4]{1}

But what if I want to match all numbers between 5 and 123 ???

Is there a syntax for that?

Answer 1

To match numbers > 5 and < 123, try:

[6-9]|[1-9][0-9]|1[0-1][0-9]|12[0-2]
