in reply to regex pattern match

Hi .. Thank you for the quick reply .. Is it somehow possible to do it without using any module...?? I've reached thus far with the code
$in_file = "test.txt"; $out_file = "testout.txt"; open (IN, "<$in_file") or die "Can't open $in_file: $!\n"; open (OUT, ">$out_file") or die "Can't open $out_file: $!\n"; while ( $line = <IN> ) { @fields = split /,/, $line; $line = join ",", $fields[0], @fields[1..5]; print OUT $line; print OUT "\n"; } close IN; close OUT; #read in output file and print to screen to confirm open (TEST, "<$out_file") or die "Can't open $out_file: $!\n"; while ( <TEST> ) { print; } close TEST;
There's only one problem bugging me .. How do i exclude the double quoted string from the pattern match in the split statement ..Once i am able to do that , the rest should be easy.. else it jus increases the amount of processing i need to do...

    what do you think about the following:

    #strip LF from line chomp $line; # delete the very first and last " from line for ($line) { s/^\s*"//; s/"\s*$//; } # now split @fields = split /"\s*,\s*"/, $line; # now you should have the pieces I mentioned above
