require 'rss'
require 'open-uri'

module RSS
class Rss::Channel::Item
install_have_child_element("index", "", "?")
end
BaseListener.install_get_text_element("", "index", "index")
end

url = 'http://www.nationalbank.kz/rss/rates.xml'
feed = RSS::parser.parse(open(url).read, false)
feed.items.each do |item|
puts item.index
