Hello nico38100

A dispatch table is useful as an hash reference is the only think the twig_handler wants: 

use strict;
use warnings;
use XML::Twig;

my %dispatch = (                      # <-- build it..
    to => sub {$_->delete;},
    from => sub {$_->set_text( uc($_->trimmed_text) ); $_->flush},
);

my $twig=XML::Twig->new(
      twig_handlers => \%dispatch ,   # <-- ..use it!
      pretty_print => 'indented',
);

$twig->parse( *DATA );

__DATA__
<note>
    <to>Tove</to>
    <from>Jani</from>
    <heading>Reminder</heading>
    <body>Don't forget me this weekend!</body>
