Subject: get index.htm and read it out

Hi,
I found this code the pragmatic programmers book.
require 'net/http'

h = Net::HTTP.new('www.pragmaticprogrammer.com', 80)
resp, data = h.get('http://www.pragmaticprogrammer.com/index.html', nil)
if resp.message == "OK"
  data.scan(/<img src="(.*?)"/) { |x| puts x }
end

So I copied this code and tried to execute it with the ruby interpreter. But
it didn't work. It just displays an errror message "private method scan
called for nil". Does anyone have a suggestion why this does not work?
Thanks
