You should return your response as a string[1], not write it to STDOUT.

What you are doing is actually sending your XML out *before* all the HTTP
handling happens; try this instead:

get '/example/' => sub {
  my $xml;
  $response->set_handler( XML::SAX::Writer->new( Output => \$xml ) );
  return $xml;

More efficient choices may also exist for getting this out the way you want.
