iOS GDataXML parsing error

[nashyo]

I'm using GDataXMLNode

NSURL *NewsFeed = [[NSURL alloc] initWithString:@"http://www.1000livesplus.wales.nhs.uk/rss"];
    NSData *xmlData = [[NSMutableData alloc] initWithContentsOfURL:NewsFeed];
    NSError *error;
    GDataXMLDocument *doc = [[GDataXMLDocument alloc] initWithData:xmlData options:0 error:&error];
    if (doc == nil) { return nil; }
    
    //NSLog(@"%@", doc.rootElement);
    News *news = [[News alloc] init];
    NSArray *extractedArticles = [doc.rootElement elementsForName:@"item"];
    
    if (extractedArticles.count > 0) {
        NSLog(@"Array contains something");
    } else {
        NSLog(@"Array is empty");
    }

In console:
NSLog(@"%@", doc.rootElement); would produce loads of xml data in console, so source is fine.

NSLog Array is empty.

i do not understand why elementsForName @"item" is not found.

The beginning of the source looks like this

i changed elementsForName @"item" to @"channel" and i got 1 step further. i found 89 'items' within that array. however, i can't find 'descriptions'...

I figured it out now. I had to extract all the items into an array, and then perform fast enumeration on that array.
