Property list

[koitohay]

Hi All,

I am completely newbee in objective c. I am trying to create property lists by reading a xml file using xml parser. works fine untill here.

But when i try to create a propertylist from this array that is holding the values i get the property list with empty data.
here is the code

- (void)viewDidLoad {
    [super viewDidLoad];
    // Uncomment the following line to add the Edit button to the navigation bar.
    // self.navigationItem.rightBarButtonItem = self.editButtonItem;
	
	appDelegate = (XMLAppDelegate *)[[UIApplication sharedApplication] delegate];
	kal = [[NSMutableDictionary alloc] init];
	
	int  count = [appDelegate.books count];
	Book *aBook;
	
	for(int i = 0; i<count; i++)
	{	
	
	aBook = [appDelegate.books objectAtIndex:i];
		kal2 = [NSDictionary dictionaryWithObjectsAndKeys:aBook.letters,@"letter",
				aBook.word,@"word",
				aBook.origin,@"origin",
				aBook.grammatical,@"grammatical",
				aBook.meaning,@"meaning",nil];
		[kal setObject:kal2 forKey:aBook.word];
		NSLog(aBook.word);
		NSLog(aBook.meaning);
		[kal2 release];
		[kal retain];
		
	}
	if([kal writeToFile:@"/Users/sk/Documents/urdudictionary" atomically:false])
	{
		NSLog(@"Success");
	}
	else
	{
		NSLog(@"Failure");
	}
