Reading RSS data for a podcast channel

The Podcast Player application starts by reading information about a number of podcast channels and their episodes:

1. First, the application reads an XML configuration file that contains a list of podcast channels and displays the list of channels to the user.

2. When the user selects one of the podcast channels, it reads the RSS feed for the channel and displays a list of the channel episodes.

This example uses the URLLoader utility class to retrieve text-based data from a remote location or a local file. The Podcast Player first creates a URLLoader object to get a list of RSS feeds in XML format from the playerconfig.xml file. Next, when the user selects a specific feed from the list, a new URLLoader object is created to read the RSS data from that feed's URL.
