In Perl you can also use XML::Twig to do pipe processing, although what is
passed around in XML, so you still have the parser penalty, you can write:

use XML::Twig;
my $twig= new XML::Twig( TwigRoots => { elt => \&handler },
                         TwigPrintOutsideRoots => 1);
$twig->parse( \*STDIN);
exit;

sub handler
  { my( $twig, $elt)= @_;
   # process element here
  }

and string several of those filters, each processing only the required
element(s).
