HTML::Summary problem

[Lee]

I've been trying to get a fairly simple (should be going. Mostly a
cut and paste of what the give on the man page. It keeps on coming up
blank for $summary:

use HTML::Summary;
use HTML::TreeBuilder;

my $tree = new HTML::TreeBuilder;

$tree->parse( 'rock.html' );
$tree->dump;
print "\n" . $tree->as_HTML . "\n";
my $summarizer = new HTML::Summary(
LENGTH => 200,
USE_META => 0,
);
$summary = $summarizer->generate( $tree );
print "Summary=" . $summary;

I'm a still a Perl newbie, so forgive the possible stupidity of this
question

btw rock.html exists in the same directory and I can open and read it
in Perl. I'm running from command line and the modules are installed.

Well, to answer my own question, changing one line of the demo program
seemed to make it work:

change:
$tree->parse( $filename );
to:
$tree->parse_file($file_name);

and it works.
