I've installed CSS::SAC on our linux box and am trying to read in a list of selectors from a specific css doc. I've read the pod and frankly don't get it. Here's what I have:

#!/usr/bin/perl -w

use CSS::SAC qw();
use CGI qw(:all);
use CGI::Carp qw(fatalsToBrowser);

my $sac = CSS::SAC->new();
my $cgi = new CGI;

# generate a stream of events
$sac->parse({ filename => 'foo.css' });

my @items = $sac->parseSelectors();

print $cgi->header();
print $sac;

foreach my $item (@items) {
    print "$item<br>\n";
}

This caused a runaway process on our server and jacked up the error log. So obviously, this isn't correct.

I get the $sac->parse statement, but what I don't get is what is meant in the pod by "sends events to the defined handlers. " What handlers are being referred to? Also, the parseSelectors($stringref) method accepts a string, but what would that be?

Any help would be greatly appreciated.
