Accessing RSS and XML Sources
Download our the required ToolsOnAir Get RSS Script.
Extract the downloaded file.
Double click the ToolsOnAir Get RSS Script. A Terminal window will appear, as seen below. The Terminal window may look slightly different on your system.
Enter or paste the URL of the RSS feed and press the enter key when you're done.
Enter the polling interval and press the enter key when you're done. Example: entering a polling interval of 10 seconds downloads a new copy of the file every 10 seconds.
The script should begin doing it's work. It downloads the specified RSS and saves it to the directory ~/Documents/CompositionBuilder (where "~" is your home directory). The script will run infinitely, even when the network connection is lost. Once the connection is re-established, the script will continue to download the RSS file. This way, the last copy of the downloaded RSS file can always be accessed – if it has been downloaded at least once.
Press control + C to stop the script. You can safely quit the Terminal application afterwards.

Click on the "…" button.
Select the RSS/XML file which was or is being downloaded by the script (the script may still be running while you use the component).
Run the composition. Make sure to sync the update interval of the component to the polling interval of the script.
