[MX]loadVars - List All Varialbes?

Hello,

Using loadVars and importing variables into Flash through a text file, is there a way to automatically list all of the variables that are in the Text file? For example say my text file had these variables:

&foo=chuck&
&mario=luigi&
&frodo=hobbit&

If I didn’t know the names of the variables foo mario and frodo, could I somehow scan the text file for all variables and simply list:

chuck, luigi and hobbit?

Thanks!
