I'm trying to create an Applescript script which essentially downloads files from Safari. However, the files are not available for download via the web page, so I usually open up the Web Inspector and then go to Resources and then in a folder called Other, download the file.
I've been searching the web for a method to do this via Applescript, but to no avail. My question is therefore: How can I access the Web Inspector > Resrouces > Other files in my current Safari window? I know that it is possible to bring up the Web Inspect using ⌥⌘I, and then you can change pane inside of the Inspector using ⌘]. But I can't get focus on the list of Resources Files, as shown below:

Is it possible to access this .mp3 file inside of the Other folder without using shortcut commands? And if not/if so, how can I access the Other folder inside of this window pane?
Thanks for your help in advance.
