Following example of xml file that contains less than and greater than symbols as entities. When output through sprint, the > entity is converted to actual symbol. The < is left alone as desired. Is this bug or option I need to set to keep the > as indicated after BAR.

#!/usr/bin/perl --
use strict;
use warnings;
use XML::Twig;
use Data::Dump qw' dd ';

Main( @ARGV );
exit (0);

sub Main {

    my %files;
    my $filename;
    my $subprint = sub {
        my( $twig, $_ ) = @_;
        push @{ $files{ $filename }}, $_->sprint;
        return;
    };
    my $twig = XML::Twig->new(
        ignore_elts => { brief => 'discard', detailed => 'discard' },
        pretty_print => 'indented',
        TwigHandlers => {
            'myroot/classes'    => $subprint,
        },
    );
    for my $file( @_ ) {
        $filename = $file;
        eval {
            $twig->parsefile( $file );
            1;
        } or warn "ERROR parsefile($file): $@ ";
    $twig->purge;
    }
dd \%files;
}
