Good Day,

I was looking at adding US zip code and city lookup to a program I'm writing, so I'm trying a quick test. I got the hard part to work (as far as I was concerned), but I'm having troubles with the simple stuff.

The following code simply passes the entered information to usps.gov and asks for the matches. It can handle either a five digit zip code, or a City, State pair. 
use strict;
use warnings;
use LWP::UserAgent;

print 'Enter Search: ';
chomp( my $x = <STDIN> );

# Create a user agent object
my $ua = new LWP::UserAgent;
$ua->agent("AgentName/0.1 " . $ua->agent);

# Create a request
my $req = new HTTP::Request POST => 'http://www.usps.com/cgi-bin/zip4/
+ctystzip2';
$req->content_type('application/x-www-form-urlencoded');
$req->content('ctystzip='.$x);

my $res = $ua->request($req);
my @matches;

my $data = $res->content;
$data =~ /----------</g;
if ($x =~ /^\s*\d{5}\s*/) {
    while ($data =~ /\G(br>((\w+\s)+\s*\w\w ))/ig) {
    push @matches, $2;
    }
} else {
    while ($data =~ /\G(br>(\d{5}))/ig) {
    push @matches, $2;
    }
}

print 'Found ',$#matches+1,' matches:',"\n  ", join("\n  ", @matches),
+"\n";

The tests tell me that what's wrong is in the "else" case, but when I put a "print pos $data" in there it prints a reasonable position.

Thanks,
