I have 3 classes-> video { nameVideo, id, description, user... } topic {nameTopic, topicID, NSMutableArray videos; } category {nameCategory, categoryID, NSMUtableArray topics}

And then in my app delegate I defined-> NSMutableArray categories;

I parse an XML file with this code. I try the arrays hierachy, and i think that i don't add any object on the arrays. How can I check it? What's wrong?

• (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict {

  if([elementName isEqualToString:@"Videos"]) { //Initialize the array. appDelegate.categories = [[NSMutableArray alloc] init]; }

  else if ([elementName isEqualToString:@"Category"]) { aCategory = [[Category alloc] init];

  aCategory.categoryID = [[attributeDict objectForKey:@"id"] integerValue];
  
  
  NSLog(@"Reading id category value: %i", aCategory.categoryID);
  

  }

  else if ([elementName isEqualToString:@"Topic"]) { aTopic = [[Topic alloc] init];

  aTopic.topicID = [[attributeDict objectForKey:@"id"] integerValue];
  
  
  NSLog(@"Reading id topic value: %i", aTopic.topicID);
  

  }

  else if ([elementName isEqualToString:@"video"]) {

  aVideo = [[Video alloc] init];
  
  
  aVideo.videoID = [[attributeDict objectForKey:@"id"] integerValue];
  aVideo.nameTopic = currentNameTopic; 
  aVideo.nameCategory = currentNameCategory; 
  
  
  NSLog(@"Reading id video value: %i", aVideo.videoID);
  

  }

  NSLog(@"Processing Element: %@", elementName); }

  [aTopic release];
  aTopic = nil;
  

  }
