Please tell me the regular expression to search for at least 2 letters per line. Letters can be located anywhere, do not have to go under the hood.

  • Letters may not necessarily be repeated, so the register is not important, and so on. The main thing is that there should be at least 2 in a row, and no matter what and in what order they are located. Example (javascript): / regular / i.test ('w89u7'); / * should return true * / / regular / i.test ('; Te153#-00'); / * should return true * / - cyberd0g

It is possible so:

.*(\w).*(\1.*)+

  • @VladD: Well, I logically reasoned. Usually they are looking for duplicates, but the phrase “it’s not necessary to go undermine,” speaks for itself. - Pavel Azanov 6:01 pm

Solution found: (?=(?:.*?[a-zA-Z]){2})

    Why is it so difficult then? Why not just \w.*\w ? - VladD

    And the most productive option for completeness :) \ w \ W * + \ w - ReinRaus
