Time for action – fetching RSS

To fetch RSS perform the following steps:

1. Create a new blank mobile app by clicking on File | New | Titanium Project. Don't use a template, as it will just generate code that gets in the way.

2. This application will be a single window app, so remove all of the code from app.js replacing it with the following:

   var win1 = Titanium.UI.createWindow({  
       backgroundColor:'#fff'
   });
   
   // open window
   win1.open();

3. Create a new file by clicking on File | New | File. Name the file rssReader.js. This file will be the CommonJS format RSS reader.

4. Create a new public function fetchRSSFeed, which will return the RSS of a given URL. Write the following code that defines the function and sets up the HTTP request:

   exports.fetchRSSFeed = function(_args) {
     var xhr = Titanium.Network.createHTTPClient();  
     xhr.open('GET', _args.url);

5. Add an event to handle what should happen if a request should fail. In this case a function will be called.

     xhr.onerror = function(e)
       {
            if...
