Hi Perlmonks.
I'm very confused with regex..:@

The partial of the input file looks like the line below: 
>sp|P49929|SC52_SHEEP 
DITCAEPQSVRGLRRLGRKIAHGVKKYG
>gi|1771590|emb|CAA70562.1| temporin B precursor MFTLKKSLLLLFFLGTINLSL
+CEEERNAEEERRDEPDERDVQVEKRLLPI

[download]

I only want to get first 2 values separated by a |
Output expected: 
sp == P49929
gi == 1771592

I try using the regex below: 
 ##$lines contains the string to be matched 
 if(/^>(\w+)\|(.*)?\|.*?$line.*\n/i){
         $flag=1;
         print OUT "$_";
         print "$1 == $2\n";    
}

It will print
sp == P49929 as expected
gi == 1771592|emb|CAA70564.1 unexpected
Any suggestion??
Thank you in advanced.
