perl regular expression question.

[Jesper]

Hi
I have a string that contains 5<= characters; two (or more) of these
charaters must be numbers - is there anyway to check this with reg. exp. ?

regards,
Jesper

Some examples could be:

ab1g3a
af884f

Here are two options:

print if ( (my $tmp = () = /(\d)/g) >= 2 );
print if tr/0-9// >= 2;

The details are in a FAQ. Just type 'perldoc -q count' from your shell.

That's just was I was looking for - thanks.

That is, you know, why FAQs exist in the first place don't you?


You could have saved the world boatloads of time if you'd looked
there _before_ asking thousands of people around the world to
go over it yet again.

Which is why netiquette suggests that you check applicable
FAQs before making a post...

Tad, come on, give that guy a break.
The Perl FAQ is quite large and it is not easy to find an answer if you
don't know what term to search for.

Quite often all that someone needs (like Jesper) is a little hint as to
_where_ to look for the answer.
He even thanked for the pointer, bashing those people is not nice.
