Code to parse Polskie Radio Lista Przebojów site and output spotify urls to make a playlist. Unfortunately, creating playlist in spotify has to be done by hand now.

lp3.rb

require 'nokogiri'
require 'open-uri'
require 'json'
require './handleData.rb'


def lista_przebojow_trojki(url=nil)
  site = Nokogiri::HTML(open(url))
  playlist = []
  site.css('#bigList tr').each do |song|
     song.css('.aT a').each_slice(2) do |s, t| 
      playlist << {artist: s.content, title: t.content}
    end
  end
  site.css('#bigListRest tr').each do |song|
     song.css('.aT a').each_slice(2) do |s, t| 
      playlist << {artist: s.content, title: t.content}
    end
  end
  site.css('#bigListRest_Unhappy tr').each do |song|
     song.css('.aT a').each_slice(2) do |s, t| 
      playlist << {artist: s.content, title: t.content}
    end
  end
  playlist
end

def proper(s)
  s.gsub!('&', 'and') if s.include?('&')
  s.split(' ').join('+')
end

#Methods has to receive playlist as array containing hasheh with keys:
#artist and title
def spotify_search(playlist=[], handler)
  playlist.each_with_index do |p, i|
    artist = proper(p[:artist])
    title = proper(p[:title])
    handler.output(nil, "#{i} #{p[:artist]} - #{p[:title]}")
    search = {'info'=>{}}
    count = 1
    begin
      until search['info'].include?'num_results' do
        url = "http://ws.spotify.com/search/1/track.json?q=#{artist}+#{title}"
        uri = open(URI.parse(URI.encode(url.strip))).read
        search = JSON.parse(uri)
        sleep(0.2)
        puts count
        count += 1
      end
    rescue OpenURI::HTTPError => ex
      handler.output(-9999, "#{url}")
    end
    if search["info"].include?('num_results') && search["info"]["num_results"] != 0
      handler.output(nil, "#{search}")

    else
      handler.output(-1, "#{p[:artist]} - #{p[:title]}")
    end
  end
end

spotify_search(playlist, handler)
