Is it possible to read the accessibilityLabel attribute of an item using AppleScript? I'm trying to extract the list of cookies according to Safari.

I have the following code fragment:

tell application "Safari" to activate
tell application "System Events" to tell process "Safari"
    keystroke "," using command down -- display preferences
    delay 1
    click button "Privacy" of toolbar 1 of window 1
    delay 2 -- let the cookie count update
    click button "Details…" of group 1 of group 1 of window "Privacy"
    get &lt;what??&gt; of row 1 of table 1 of scroll area 1 of sheet 1 of window "Privacy"
end tell


Which is fine except that I can find no way to get the cookie name from the row. Tantalisingly, however, VoiceOver can read the value and Accessibility Inspector shows it to be held in the accessibilityLabel attribute.

Hence the question: is there a way of getting the value of the accessibilityLabel attribute in AppleScript?

Versions: Safari 9.0 / El Capitan.

PS: I know there is a Cookies.binarycookies file in the user's library. I'd still like the answer to my question for future reference at least!
You can access the 'description' of the 'UI Element' of each row. Like so:

tell application "Safari" to activate
tell application "System Events" to tell process "Safari"
    keystroke "," using command down -- display preferences
    delay 1
    click button "Privacy" of toolbar 1 of window 1
    delay 2 -- let the cookie count update
    click button "Details…" of group 1 of group 1 of window "Privacy"
    set z to description of UI element 1 of every row of table 1 of scroll area 1 of sheet 1 of window "Privacy"
end tell
return z
