You want to loop over the URLs, with the fetch inside the loop. 

my @urls = (
    "http://localhost:8080/html.htm",
);

for my $url (@urls) {
    my $html = get($url) 
        or die "Couldn't fetch page.";

    $html =~ ...
    ...
}

Or if you plan on adding to @urls, 

my @urls = (
    "http://localhost:8080/html.htm",
);

while (@urls) {
    my $url = shift(@urls);

    my $html = get($url) 
        or die "Couldn't fetch page.";

    $html =~ ...
    ...
    push @urls, $new_url;  # or @new_urls
    ...
}

Using push results in a breadth-first search.
Using unshift results in a width-first search instead.
The former is almost surely most desirable here.
