Question

I would like to pull the titleand description fields from the newsfeed at http://www.tagesschau.de/newsticker.rdf to feed them to the Mac’s Text-to-Speech engine.

My search for a nice Ruby Gem to do this has brought me to Nokogiri, but all examples that “pull something out” of a given XML seem to be centered around CSS somehow.

Does anyone have any idea how to save the titleand description fields in an array?

Answer 1

Use xpath / at_xpath (the latter returns only one element):

require 'nokogiri'
require 'open-uri'
require 'pp'

entries = []
doc = Nokogiri::XML(open('http://www.tagesschau.de/newsticker.rdf'))
doc.xpath('/rss/channel/item').each do |item|
  entries << [item.at_xpath('title').text(), item.at_xpath('description').text()]
end

pp entries
