Heh, it actually works currently though. That is a straight copy from
my running code.
Oh, I get it now! selectedObjects is obviously an array, so when I
send valueForKey:@"xml" to it, I get an array of the results of that
call on each element - thus requiring lastObject.
So really the lastObject can go either place. Thanks!

Well, yes.
You ask your xml for lastObject. That won’t work.
What you want is this:
[[[treeController selectedObjects] lastObject] valueForKey:@"xml"]
Ask the array for its lastObject, then get the xml out of it ;)
