ou want this? my ($seq) = ($var =~m/^(.*_{0,1}\d+)\s.*?/); adding the '?' makes the * stop after the first time the regex was found Tine Op 16-apr-09, om 17:30 heeft Esther-Kristin Lather het volgende geschreven:
Hi!
How can I make this Regex greedy?
my ($seq) = ($var =~m/^(.*_{0,1}\d+)\s.*/);
if $var is "ara_prot.tfa_3154 | AT1G26170.1 | no family", I want to cut after the first whitespace so that $seq becomes be "ara_prot.tfa_3154" and not "ara_prot.tfa_3154 | AT1G26170.1".
I don't know where/ how to include the ? for non-greedy search. I would want to do it with round brackets, but that violates the round brackets I already use for getting a part of the string, no?
Thanks for any suggestions! Esther. _______________________________________________ Binari Implicitly Neglects All Recursive Iterations https://maillist.psb.ugent.be/mailman/listinfo/binari
