[Israel.pm] XML processing problem

Hello,

Please consider the following code snippet:

	use XML::Twig;

	my $twig=XML::Twig->new(
		twig_roots => {
			item => \&handle_item
		},
		twig_print_outside_roots => 0,
		keep_encoding =>1,
	);
	$twig->parsefile( 'myfile.xml' );
	$twig->flush; # flush the end of the document

	sub handle_item {
		my( $twig, $item)= @_;
		# do something with $item
	}


I was surprised to see that this code prints *some* of my
XML file, although 
	twig_print_outside_roots => 0

Moreover, it seems that all the file is being processed and
only then output (the output I don't even want) is being
printed to the standard output. This is although this method
should be processing the XML one 'item' at a time without
building the twig of the whole xml file.

Any ideas what's going on?
