%@ calls the "description" method of the object you pass it.

NSString* currentKey = (NSString*) [ myTree childAtIndex:0]);
NSLog(@"%@", currentKey); // This also produces an "Archive Path"

Same here, and you're just lucky because your type-casting an XMLTree to an NSString, but since both implement "description", NSLog() doesn't care.

if ([ currentKey isEqualToString:@"Archive Path"]) // THIS, however, produces a runtime error "[ XMLTree -isEqualToString:] selector not found"

Yes, because XMLTree != NSString.

Long story short: -childAtIndex: returns another XMLTree, but obviously it also holds the correct value (see the NSLogs above). Since there is no method in the class for explicitly returning the element value, is there ANY way I can get my comparison working?

Since "description" apparently returns the value, you could probably just use:

NSString* currentKey = [[myTree childAtIndex:0] description];
And then work with that?

Though it *does* seem kind of weird that XMLTree wouldn't have a method that returns its name, if its description returns such a name. Make sure you didn't just miss it before relying on description, because IIRC there are no guarantees as to the format of its value.
