Regex number and hyphen

Question

I\'m trying to match number with regular expression like:

34-7878-3523-4233

with this:

^[0-9][0-9-]*-[0-9-]*[0-9]$
<         


        

Answer 1

That's because, you have included the hyphen in the allowed characters in your character class. You should have it outside.

You can try something like this: -

^([0-9]+-)*[0-9]+$

Now this will match 0 or more repetition of some digits followed by a hyphen. Then one or more digits at the end.
