And now of course I have to add my onw take to it!

All you want to do is change some img tags, while leaving the rest of the file unchanged. This looks like a good opportunity to use twig_roots, which only builds the twig for the elements that have handlers, and the awfully named twig_print_outside_roots, that prints everything else in the document:

#!/usr/bin/perl -w
use strict;
use warnings;
use XML::Twig;

my $twig = XML::Twig->new(
   twig_print_outside_roots => 1, 
   twig_roots => {
      'img[@alt="Smiley"]' => sub { print q{:)} },
      'img[@alt="Wink"]'   => sub { print q{;)} },
   },
);

$twig->parse(\*DATA);

__DATA__
<body>
<a href="wink.html"><img border="0" src="/images/wink.gif" alt="Wink"/
+></a>
<a href="wink.html"><img border="0" src="/images/wink.gif" alt="NotWin
+k"/></a>
<a href="smile.html"><img border="0" src="/images/smiley.gif" alt="Smi
+ley"/></a>
</body>
