Indeed, the docs aren't very clear on how things work. Nevertheless, I managed to create a small example of how to get to the content of entries:

#!/usr/bin/perl

use strict;
use warnings;

use XML::Atom::Feed;
use XML::Atom::Entry;

use Text::Wrap;

my $feed = XML::Atom::Feed->new("/home/arjen/atomfeed.xml");
foreach my $entry ($feed->entries()) {
    print "* ", $entry->title(), "\n";
    my $body = $entry->content()->body();
    $body =~ s/^\s*//g;
    $body =~ s/\s*^//g;
    print wrap('', '', $body), "\n\n";
}

The file /home/arjen/atomfeed.xml is a file with the contents of the Atom feed of Perl.com. You'd have to change to your own file, of course :-)

It isn't HTML, but I think this is a nice starting point.
