Trying to capture XML data and convert to a String...

[R]

I'm new and in the process of learning Objective-C and Cocoa.

I want to take some raw XML data, isolate, and convert to a string.  I seem to 
be able to capture the data I want, but cannot seem to get into a string 
format.  Actually, I will want in a NSMutableString format… but am keeping 
things simple for now.

Here is an excerpt of my code:

The problem is at the end of the code below….  the string findAlerts is empty.  
The NSXMLElement specificAlert prints correctly.

Thanks for your thoughts and patience….

Note: Previous initialization:
        NSXMLDocument *gameStatusXML;
        NSArray *myGames;


@implementation ScoreEngine

-(NSData *)loadData{
                
                NSLog(@"loadGameData executed");
                
                NSString *urlString=[NSString stringWithFormat:
