I'm trying to parse a call from Geonames with NSXMLParser in the iPhone SDK. I've used this before but for some reason I'm getting an empty dictionary back even though I get results back in a web browser. Can someone please point out what I may be doing wrong.

Below is the code I'm using and the results that comes back pasting it in a browser.

Thanks in advance

 #pragma mark -
#pragma mark - Parcer Services

-(void)beginLoadingFeed{
 //[self startLoadingWithMessage:@"Loading Results...."]; 
 NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(loadFeed) object:nil];
 [operationQueue addOperation:operation];
 [operation release];
}

- (void)loadFeed{
 NSString *path = [NSString stringWithFormat:@"http://ws.geonames.org/postalCodeSearch?placename=%@&long&maxRows=20",self.location];
 [Logger log:@"Geonames Query: %@",path];
 [self parseXMLFileAtURL:path]; 
 [self performSelectorOnMainThread:@selector(didfinishedLoadingFeed) withObject:nil waitUntilDone:YES];
}

-(void)didfinishedLoadingFeed{

}

- (void)parserDidStartDocument:(NSXMLParser *)parser{ 
 [Logger log:@"found file and started parsing"]; 
}


//Called when the parser runs into an open tag (<tag>)
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict {

 if ([elementName isEqualToString:@"code"]) {
  currentResult = [NSMutableDictionary dictionary]; 
 } else {
  currentElement = [elementName copy];
 }

}

//This is just to resolve random HTML entities
- (NSData *)parser:(NSXMLParser *)parser resolveExternalEntityName:(NSString *)entityName systemID:(NSString *)systemID {
 return [entityName dataUsingEncoding:NSASCIIStringEncoding];
} 


- (void)parseXMLFileAtURL:(NSString *)URL{ 
 self.results = [[[NSMutableArray alloc] init] autorelease];
 NSURL *xmlURL = [NSURL URLWithString:URL];
 NSXMLParser *parser = [[NSXMLParser alloc] initWithContentsOfURL:xmlURL];
 [parser setDelegate:self];
 [parser parse];
 [parser autorelease];
}

- (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError {
 NSString * errorString = [NSString stringWithFormat:@"Unable to connect to web site (Error code %i )", [parseError code]];
 [Logger log:@"error parsing : %@", errorString]; 
 [self stopLoadingView];
 [self showMessage:@"Error loading content" withTitle:@"Error Loading"];
}



/*** Called when the parser runs into a close tag (</tag>). If it is the Result tag that is closing, we should add the currentResult to the array, and then forget about it ***/
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
 if ([elementName isEqualToString:@"code"]) {
   [self.results addObject:currentResult];
   currentResult = nil;
 }
}


- (void)parserDidEndDocument:(NSXMLParser *)parser {
 [Logger log:@"all done!"]; 
 [Logger log:@"results array has %d items", [self.results count]];
 [Logger log:@"Results:%@",results];
 [theTableView reloadData];
 [self stopLoadingView];
}

Below is the result that comes back in a browser using the same call above when doing the search for the term "boston":
