An RSS generator for CBC Channels

This isn’t perfect (seems to fail on some feeds), but mostly works for me:

#!/usr/bin/perl -w
# cdf2rss - converts CBC KlipFarm CDF to crude RSS
# created by scruss on 02004/11/12
# RCS/CVS: $Id: cdf2rss,v 1.3 2004/11/13 03:59:21 scruss Exp $
# takes one argument, a stream name. Currently known streams are:
# Arts Business Calgary Canada
# Edmonton Montreal Ottawa
# Science Sports Toronto
# Vancouver Winnipeg World
# returns a crude RSS 1.0 stream fashioned from the CBC CDF output.
use strict;
use integer;
use XML::Simple;
use XML::RSS;
use LWP::Simple;
use constant CDFURL => '';
my $cdf = get( join( '?lineup=', CDFURL, $ENV{'QUERY_STRING'} ) );
my $xs = new XML::Simple;
my $ref = $xs->XMLin($cdf);
my $rss = new XML::RSS( version => '1.0' );
title => join( ' ', 'CBC', $ref->{category} ),
description => join( ' ', 'CBC', $ref->{category} ),
link => $ref->{href}
foreach my $cdf_item ( @{ $ref->{item} } ) {
my $tmp_abstract = $cdf_item->{abstract};
$tmp_abstract =~ s/\s+/ /g;
$tmp_abstract =~ s/^ //;
$tmp_abstract =~ s/ $//;
title => $cdf_item->{title},
link => $cdf_item->{href},
description => $tmp_abstract
print "Content-type: application/xml+rss\n\n", $rss->as_string;


  1. thanks for this…but any tips on putting the code to good use? i’ve messed around with it a bit (i don’t really know squat about perl), but the most practical thing i’ve been able to do is run the code on my c: drive (altered the code to write an .xml file) & generate live bookmarks in firefox (but only for the Arts feed, which appears to be the default — i’m still trying to figure out how to pass an argument to perl from the command line). oh, and one bug: the <description> contents are missing all their s’s…

  2. As it stands, it’s designed to run from a server. You access the feeds
    by calling something like:


    for the Edmonton or World Feeds.

    If you want to generate a file, change the line that reads:

    my $cdf = get( join( ‘?lineup=’, CDFURL, $ENV{’QUERY_STRING’} ) );


    my $cdf = get( join( ‘?lineup=’, CDFURL, $ARGV[0] ) );

    and the line:

    print “Content-type: application/xml+rss\n\n”, $rss->as_string;


    print $rss->as_string;

    Then you could run it like:

    cdf2rss Toronto > cbc_toronto.xml

    The missing sibilant problem was down to WordPress eating ‘\’ characters. It’s fixed on the page now, thanks.

  3. Thanks, but you’re going to have to spell it out for a me a bit, if you don’t mind. I’ve saved this as .pl and .cgi and I still get a 500 and a 404 every time I try to call the file as you suggested.

    What do I have to save it as?
