Question

I am using NSXMLParser to parse this XML: http://itunes.apple.com/gb/rss/topsongs/limit=50/explicit=true/xml. I am trying to parse an element called “im:image”. My problem is that there are three elements with the name “im:image”. How can I only parse the data from the second “im:image”, or how can I add each single one to an array?

In the didStartElement method of your custom delegate, check attributes and ensure that it has height set to 60 (each of the ‘same’ XML elements has a different height attribute). The attributes is an NSDictionary with keys for name of the attributes and values for values of the attributes. Here is an example of roughly how you would do it:

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict {
  if ([[attributeDict objectForKey:@"height"] isEqualToString:@"60"]) {
    NSLog(@"store");
  }
}
