itunes_parser

A ruby library for parsing iTunes XML library files based on nokogiri.

Examples

Using generated xml.

Regular usage

>> parser = ItunesParser.new( open("fake_itunes.xml") )
>> parser.tracks.map {|track| track["Name"] }
=> ["Test song name 0", "Test song name 1", "Test song name 2", "Test song name 3", "Test song name 4"] 
>> parser.playlists.map {|playlist| playlist["Name"] }
=> ["Test playlist 0", "Test playlist 1", "Test playlist 2", "Test playlist 3", "Test playlist 4"] 

With callbacks

>> file = open("fake_itunes.xml")
>> on_track = lambda {|track| puts "on_track: #{track["Name"]}" }
>> ItunesParser.parse(file, :on_track => on_track)
on_track: Test song name 0
on_track: Test song name 1
on_track: Test song name 2
on_track: Test song name 3
on_track: Test song name 4

>> file = open("fake_itunes.xml")
>> on_playlist = lambda {|p| puts "on_playlist: '#{p["Name"]}' has #{p["Playlist Items".size]} tracks" }
>> ItunesParser.parse(file, :on_playlist => on_playlist )
on_playlist: 'Test playlist 0' has 5 tracks
on_playlist: 'Test playlist 1' has 5 tracks
on_playlist: 'Test playlist 2' has 5 tracks
on_playlist: 'Test playlist 3' has 5 tracks
on_playlist: 'Test playlist 4' has 5 tracks
