Defaults just can't do it.
Parse it or use an xml translation tool.

Has this ever been answered? I need to retrieve info that is deeper
than 1 level into the plist. Is it possible without grep/parsing
routines? If so, a simple example would be GREATLY appreciated.

Ok, trying to answer a question about getting the current audio
system volume level I used defaults read to get one layer down into
the plist data.
set fileRef to POSIX path of (((path to startup disk) as string) &

set vData to do shell script "defaults read " & fileRef & " Devices"

InputDevices = {
\"AppleDBDMAAudioDMAEngine:0\" = {Balance = 0; DeviceLevels =

Level = 0.5;

--I can parse it...
set AppleScript's text item delimiters to "Level = "
set vol to word 1 of text item -1 of vData
--"0.5"
--but does anyone know the proper syntax for getting directly to any
layer below the topmost? Such as the OutputDevices?
set vData to do shell script "defaults read " & fileRef & " Devices
OutputDevices"
-->nope
set vData to do shell script "defaults read " & fileRef & "
Devices/OutputDevices"
--nada.
set vData to do shell script "defaults read " & fileRef & "
Devices;OutputDevices"
-->nutin.
