I have this pattern .*?[az]([az])([az])([az]).*?(\\s+)(\\d+)
from some online generator but it's not working.
I need pattern which allow:
"minimum 3 char length string, next single space, and next minimum 1 char integer" [abc 1] or the same but in different order "minimum 1 char integer, next single space, and next minimum 3 char length string" [3 gtf].
Thanks.
Try this one:
\d+\s\w{3,}|\w{3,}\s\d+
It either matches:
\\d+
), followed by a single whitespace ( \\s
), followed by three or more word characters ( \\w{3,}
) (this is [a-zA-Z0-9], you can replace this part with [a-zA-Z] if you'd like). The following expression should do what you describe:
[a-z]{3,}\s\d+|\d+\s[a-z]{3,}
Some notes:
The {3,}
construct allows you to specify repetitions within a given range. In general, it's {min,max}
, but you can leave out either min or (as here) max to have an open-ended range. You can also specify an exact number of repeats by specifying a single number, eg {99}
.
The expression is essentially two complete expressions switched with alternation. Regular expressions don't allow you to say "exactly these things, in any order".
I've used [az]
to match the characters in the non-numeric part, as this is what you did in your original example.
