Ok, I might simply be less than smart here, and the answer is probably 
obvious, but I can't see it. The basic issue is: I have an NSData 
object and want to store it in an XML node, then later restore it from 
an XML node. Lots of sifting through documentation and usually helpful 
internet sites and generally making the cogs in my brain groan, squeak 
and creak for the better part of yesterday and today yielded no usable 
results.

I know how to (un)archive NSData objects to/from disk and user 
defaults, but am not sure how to turn them into strings (to store in 
XML elements) and especially how to restore them from strings that 
represent NSData objects.

Any help would be greatly appreciated.
