Regex: How to match a string that is not only numbers

Question

Is it possible to write a regular expression that matches all strings that does not only contain numbers? If we have these strings:

• abc

Answer 1

Since you said "match", not just validate, the following regex will match correctly

\b.*[a-zA-Z]+.*\b

Passing Tests:

abc
a4c
4bc
ab4
1b1
11b
b11

Failing Tests:

123
