Re: Find repeating substring

Thus spoke Mike (on 2006-06-20 16:19):

Hmm. This seems very close. It still picks up the code (37.33/2) that
is not repeated, but let me play with this a bit to see if I can
exclude that.

It doesn't here, consider:


my $text = <<END_OF_TEXT;
HEART (CONDUCTION DEFECT) 37.33/2 HEART (CONDUCTION DEFECT) WITH
CATHETER 37.34/2
END_OF_TEXT

my $rep = qr{ ^(.+)(?=\s*).*?\1 }msx;
my ($repeated) = $text=~/$rep/;

print $repeated;



prints: HEART (CONDUCTION DEFECT)


(BTW: I made the final .* non-greedy)
