Use something like /\",\"/ for your regexp. Be careful, though... presumably your string looks like '"alpha","beta","gamma"'. Using split will leave the leading and trailing double quote on the first and last elements, respectively. For example:

#!/usr/local/bin/perl

my @items = split /\",\"/, '"alpha","beta","gamma"';

foreach (@items) {
    print "$_\n";
}

will spit out

"alpha
beta
gamma"
[download]

Just make sure you deal with those at some point; I'd probably do something like substr $string, 1, -1 If there's extra garbage in the string, maybe like <CODE>s/\"(.*)\"/$1/</CODE
