How do you write basic start_element, character, end_element handler events in XML::Twig similar to how it is done in XML::Parser as shown here: 
    #!/bin/perl
    use strict;
    use warnings;
    use XML::Parser;
    my %elements;

    my $parser = XML::Parser->new( Handlers => 
                       {
                        Start=>\&handle_start,
                        End=>\&handle_end,
                        Char=>\&char_handler
                       });

    # specify xml file on command line
    foreach my $file ( @ARGV ) {
      eval { $parser->parsefile( $file ) };
      die "can't parse file: $@"   if $@;
    }

    sub handle_start {
        my( $expat, $element, %attrs ) = @_;
        if( %attrs ) {
        print "\t$element attributes:\n";
            while( my( $key, $value ) = each( %attrs )) {
              print "\t\t$key => $value\n";
            }
        }
    }

   sub char_handler
    {
        my ($p, $data) = @_;
        my $inf = $elements{$p->current_element};
        if ($data =~ /\S/) {print "\t$data\n";}
    }

    sub handle_end {
        my( $expat, $element ) = @_;
        # print "$element\n";
    }
