I'm looking at the following code, I can't figure out why: print "$1\n"; works. Where is $1 coming from?
use strict;
use LWP 5.64;
my $browser = LWP::UserAgent->new;
my $url = 'http://www.cpan.org/RECENT.html';
my $response = $broswer->get($url);
die "Can't get $url -- ", $response->status_line
unless $response->is_success;
my $html = $response->content;
while( $html =~m/<A HREF=\"(.*?)\"/g) {
print "$1\n";
}
How is $1 getting its value?
This some example code from the book "Spidering Hacks" and I'm not sure if it's a typo or something I'm missing.
Thanks
Adam
Update: Ahh I see, m//the expression is returning a list of matched values, with the first match it stores the (.*?) value at $1. Got it. Thanks.
