GDataXML parsing error

i'm using gdataxmlnode

code:

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 empty");     }

in console:
nslog(@"%@", doc.rootelement); produce loads of xml data in console, source fine.

nslog array empty.

not understand why elementsforname @"item" not found.

beginning of source looks this

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

 

i figured out now. had extract items array, , perform fast enumeration on array.
