how to get 1-100 using regex

Question

I'm trying to get something like:

    Hello, 0 ( dont get )
    Hello2, 100 ( get )
    hello3, 82 ( get )
    hello< 132 ( dont get )

I've made something like this so far:

[a-zA-Z]{1,255},([0-9]{1,3})(?<![0])

But it can't get 132 and 100. How can I fix this?

Answer 1

Try this regex which matches a number of 1 or 2 digits, or 100:

\d{1,2}(?!\d)|100

Answer 2

Why not keeping it simple?

^[a-zA-Z]{1,255}, (100|[1-9][0-9]|[1-9])$

or better yet

^[a-zA-Z]{1,255}, (100|[1-9][0-9]?)$

note: this won't match prepended zeros e.g. "Hello, 00001". It can be easily extended, though:

^[a-zA-Z]{1,255}, 0*(100|[1-9][0-9]?)$
