How to match a whole string that contains just two and no more than two digits between 0 and 10 in regex?

Question

This regex does not work for me as selects all groups of two and multiple digits and not the string.

abcde9 = match
abcde12 = not matched
abcde12345678 = not matched

What I have at the moment is this, it I just can't include the 0 and the 10 as two digits numbers in the regex, can anyone help me?

\d{0,10}[1-9]

Answer 1

Is that what you looking for:

/(0[1-9])$/

You can test that regex to make sure it fits your needs: https://regex101.com/r/hX6lB7/3

Answer 2

I think you are looking for

^\D*(?:[0-9]|10)(?:\D+(?:[0-9]|10))?\D*$

See demo

This will match a whole string that contains 1 or 2 whole integer numbers from 0 to 10, and no other digits.

The regex breakdown:

• ^ - start of string
• \\D* - 0 or more characters other than digit
• (?:[0-9]|10) - numbers from 0 to 10
• (?:\\D+(?:[0-9]|10))? - 1 or 0 occurrence of
  • \\D+ - 1 or more characters other than digit
  • (?:[0-9]|10) - numbers from 0 to 10
• \\D* - 0 or more characters other than digit
• $ - end of string

Answer 3

If you want to match any string containing exactly one integer from 0 to 10 then use

^\D*(\d|10)\D*$

which means "any non-digit content followed by either a single digit or the number 10 and then followed by any non-digit content"
