Hi Archana, try like this,

use strict; use warnings; my $str ='"Transcription factor" promoter DNA "Transcription factor" p +romoter DNA.'; my @str = split//, $str; my $fla = 1; for (@str){ if (($_ eq "\"") && $fla) { $fla = 0; }elsif (($_ eq "\"") && !($fla)){ $fla = 1; } $_ =~ s/ /\,/ if ($fla); } print join'',@str; __END__ Output: ------- "Transcription factor",promoter,DNA,"Transcription factor",promoter,DN +A.

TIMTOWTDI, we can achieve the expected output using RegExp as of below:

$str =~ s/((?:(?!\").)*)(\"[^\"]+\")((?:(?!\").)*)/ my $fi = $1;my $se = $2; my $th = $3; $fi =~ s| |\,|g;$th =~ s| |\,|g; "$fi$se$th"/egs;

Regards,
Velusamy R.


eval"print uc\"\\c$_\""for split'','j)@,/6%@0%2,`e@3!-9v2)/@|6%,53!-9@2~j';
