I am learning a Mojo::UserAgent module and I've stumbled upon an issue, that I can't find an answer to on the internet and Mojo's mans.

Here is the test code: 

#!/usr/bin/env perl
use utf8;
use feature 'say';

use Mojo::UserAgent;

my $data = undef;

#Get correct file
my $cache = shift // '/tmp/cache.html';
if(-d $cache){
    die("'$cache' is folder. You need to use file.");
}

if(-e $cache){
    $data = Mojo::File->new($cache)->slurp;
}else{
    say 'Fetching fresh HTML';
    my $ua = Mojo::UserAgent->new;
    my $tx = $ua->get('https://www.mojolicious.org');
    die "Could not fetch! Error is ", $tx->result->code unless($tx->re
+sult->is_success);
    $tx->result->content->asset->move_to($cache);
    $data = $tx->result->body;    #->body is not only <body>...</body>
+, but a complete loaded resource content for 1 file.
}

say "Tags are:\n\t", Mojo::DOM->new($data)->find('a')->map(attr=>'href
+')->uniq->sort->join("\n\t");

It works, but, is there a way to list the existing attributes from a given tag?
I tried to find it out from Mojo:
:DOM
:Asset
:Content
and I didn't find any mentioning of attr enumeration or conversion to string.
Is there a way to find out what tags exist on found tag?

Something like this, probably?: 

Mojo::DOM->new($data)->find('a')->map(attr=>'*')->join("\n\t");

I tried to enumerate with: 
my %attrs = "Tags are:\n\t", Mojo::DOM->new($data)->attr;
map{ print "(%s)/(%s)\n", $_, $attrs{$_} } sort keys %attrs;

But I only got empty hash.

UPDATE

OK, i've figured it out: 
my $dom = Mojo::DOM->new($data);
map{ say }  $dom->find('a')->first;
my $attrs = $dom->find('a')->first->attr;
map{ printf "(%s)/(%s)\n", $_, $attrs->{$_} } sort keys %$attrs;
