in reply to Strip user-defined words with regexp

I would do it this way. I don't know if it deserves an high grade, but it gets the job done :).

my $count = 0; while ( $message =~ /([A-Za-z0-9]+)/g) { last if $count++ > 1; print "$1\n"; }

    rnahi,
    "but it gets the job done :)."

    Sorry to nitpick, but actually it doesn't. The first two words were being desired of each sentence.

    Updated to clarify Updated is in italics. I am still wrong because of a misinterpretation of the OP's requirements.

      Did you try it?

      It prints the first 2 words as defined by the OP.

        rnahi,
        Yes I did - against the $msg in my post. The problem is my original understanding of the OP's requirements. I was thinking there would be multiple sentences in a given string and the first two words of each sentence was required. There has been clarification of the requirements and you are correct - sorry.

        Cheers - L~R

      I think my original post was a bit too unclear.

      I am looking for at most the first two words. So it may be zero, one or two.

      I've modified his code to:
      my $firstWord = undef; my $secondWord = undef; my $i = 0; while ($message =~ /([A-Za-z0-9]+)/g) { if ($i == 0) { $firstWord = $1; } elsif ($i == 1) { $secondWord = $1; last; } $i++; }
      which does exactly what I was looking for. I only tried to do it in one regexp.

      Thanks, Marcel
