Hi, all...

I used to use "feedtools" (now defunct) and I am trying to switch over
to the RSS stdlib.

Can anyone tell me why this doesn't work? (Error below)

Thanks,
Hal


require 'rss'
require 'open-uri'

URL = "http://feeds.space.com/SpacecomUniversalSpacePodcast"

rss = open(URL).read
feed = RSS::Parser.parse(rss)
puts "Description: #{feed.title}"
feed.items.each.with_index {|item,i| puts "#{i+1}. #{item.title}" }


Error is:
