YouTube Playlist in Titanium

In this post I am going to discuss about how to fetch YouTube playlist from a channel using Appcelerator Titanium.

YouTube offer API for category, search term, playlist, favorites, subscriptions... etc. Here you can found list of YouTube API
https://developers.google.com/youtube/getting_started

Below API will retrieve the user's playlists. This request does not require authentication
https://gdata.youtube.com/feeds/api/users/userId/playlists?v=2

* Here  userId represents YouTube username.

The above API response containing a playlists feed in XML format.
The response contains a series of <entry>  tags, with each entry describing a playlist.
Each entry contains the playlist's title, description, author and modification date as well as
a  <content> tag that specifies the URL for retrieving the list of videos in the playlist

Here I am  using Apple's YouTube username to fetch their YouTube playlist

var channelName = "apple";
var loader = Titanium.Network.createHTTPClient();
loader.open("GET", "http://gdata.youtube.com/feeds/api/users/"+channelName+"/playlists?v=2");

loader.onload = function() {
 var doc = this.responseXML.documentElement;
 var items = doc.getElementsByTagName("entry");
 for (var i = 0; i < items.length; i++) {
   var item = items.item(i);
   var playlist_title = item.getElementsByTagName("title").item(0).text;//playlist title
   var vid_count = item.getElementsByTagName("yt:countHint").item(0).text; //video count for this playlist
   var play_list_id = item.getElementsByTagName("yt:playlistId").item(0).text; //play_list_id
 }
};

loader.onerror = function(e) {
 alert("Error:"+e.error);
};

loader.timeout = 10000;
loader.send();

In below code I am going to retrieve all the videos in a particular playlist using playlist id.
http://gdata.youtube.com/feeds/api/playlists/playlist_id?v=2

var loader = Titanium.Network.createHTTPClient();
loader.open("GET", "http://gdata.youtube.com/feeds/api/playlists/" + playlist_id + "?v=2");

loader.onload = function() {
  var doc = this.responseXML.documentElement;
  var items = doc.getElementsByTagName("entry");
  for (var c = 0; c < items.length; c++) {
   var item = items.item(c);
   var thumbnails = item.getElementsByTagName("media:thumbnail");
   if (thumbnails && thumbnails.length > 0) {
     var media = thumbnails.item(0).getAttribute("url"); //thumbnail image
     var title = item.getElementsByTagName("title").item(0).text; //video title
     var videoId = item.getElementsByTagName("yt:videoid").item(0).text; //video id
   }
  }
};

loader.onerror = function(e) {
 alert("Error:" + e.error);
};

loader.timeout = 5000;
loader.send();
