Yup, start_tag_handlers is enough, but the flushing has to be done from end_tag_handler
#!/usr/bin/perl --
use strict; use warnings;
use XML::Twig;
my $str = <<'EOF';
<NoTe KunG="FoO" ChOp="SuEy">
<To KunG="FoO">
<Person KunG="FoO">Satan</Person>
</To>
<Beef KunG="FoO"><SaUsAGe KunG="FoO">is Tasty</SaUsAGe></Beef>
</NoTe>
EOF
{
my $t = XML::Twig->new(
pretty_print => 'indented',
force_end_tag_handlers_usage => 1,
start_tag_handlers => {
_all_ => sub {
$_->set_tag( lc $_->tag );
if( $_->has_atts ){
my $atts = $_->atts ;
$_->set_atts ({
map {
lc( $_ ) => $atts->{$_}
} keys %{ $atts }
});
}
return
},
},
end_tag_handlers => { _all_ => sub { $_->flush; return }, },
);
$t->parse($str);
$t->flush();
}
__END__

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
