Example for querying 3sat.de mediathek in Ruby - did not get HD material though

mediathekview-3sat-de.rb

require 'nokogiri'
require 'open-uri'

# 3SAT rss feed url
rss_feed = "#{base_uri}/rss/mediathek.xml"

# 3SAT webservice

# Video type and such
VIDEO_TYPE = "h264_aac_mp4_http_na_na"
QUALITY = "veryhigh"

# open rss feed
doc = Nokogiri::XML(open(rss_feed))

# parse xml
rss_items = doc.xpath("//rss//channel/item")

# loop though each item
rss_items.each do |rss_item|
  title = rss_item.at_xpath(".//title").text
  link  = rss_item.at_xpath(".//link").text
  
  # we need this later:
  # we could also use URI class but... this is simpler and
  # does not need additional libraries
  media_id = link.split('=')[1]

  # build detail uri and open it
  xml = Nokogiri::XML(open("#{detail_uri}#{media_id}"))
