puts "=== Channel: #{feed.channel.title} ==="
feed.items.each do |item|

but as you see i can't change the feed
and i need the value of <index> item.

What is <index>? Who does define <index>?

is there any way to get the value of <index> item

  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&#39;
  feed = RSS::Parser.parse(open(url).read, false)
  feed.items.each do |item|
    puts item.index
  end

Thanks,
