xmlparser parse returns no always, how to fix?

NSURL *url = [[NSURL alloc]   initWithString:@"..."];
NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithContentsOfURL:url];


//Initialize the delegate.
XMLParser *parser = [[XMLParser alloc] initXMLParser];

//Set delegate
[xmlParser setDelegate:parser];


//Start parsing the XML file.
BOOL success = [xmlParser parse];

if(success)
    NSLog(@"No Errors");
else
    NSLog(@"Error Error Error!!!");

returns no . Why is that happening?

output: Error Error Error!!!

If you implement the parseErrorOccurred: method in your delegate XMLParser class, it will give you the exact reason for the errors.

Something like:

- (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError {
    NSLog(@"NSXMLParser ERROR: %@ - %@", , [parseError localizedDescription], [parseError localizedFailureReason]);
}
