another regex question
i am reading a file and found a line i want that is stored in $line:

$db_name = "Bidders - Private";

i want to get rid of everything except what's inside the quotes: Bidders - Private. that is i want to remove $db_name = " and the "; at end of line. i can't figure out how to do it!

thanks

Hi,

Without knowing much more, this should do the trick:

Code:
my @loop = split /\n/, q|
some line
$db_name = "Bidders - Private";
more values|;

my $db_value;
foreach (@loop) {
m/\$db_name = "(.+?)"/ and $db_value = $1;
}
print "GOT: $db_value \n";

Tested that locally, and all looks good Angelic

Cheers

i figured out a way to get what i wanted:

($dispname1,$dispname2,$dispname3) = split (/\"/, $dispname);

$dispname2 is the part i want!

sorry but i couldn't understand what you gave me but i'm sure it was more elegant than mine! thanks!

This is probably what you want instead Smile

Code:
if ($line =~ /^\$db_name/ ) { $line =~ m/\$db_name = "(.+?)"/ and $dispname = $1; }

$dispname would then hold the value between the " and "

Cheers
