RSS Feed within a Tabbed Application

I'm a new app developer who's in the process of creating a basic tabbed Android application using JavaScript with Titanium Studio. I would like to incorporate the RSS feed from a website into one of the windows within my application. I have downloaded the RSS Reader sample application and have tried to decipher the code, but given my limited knowledge of JavaScript I have encountered difficulties. I was wondering if someone would be able to help me with the code in order to help me achieve this. The basic code for the window in question is below. Any help would be greatly appreciated, thanks in advance.

function NewsWindow(title) {
    var self = Ti.UI.createWindow({
        title:title,
        backgroundColor: '#336699'
    });
 
 
 
return self;
}
 
 
module.exports = NewsWindow;
