UITableview not display data

Question

Hey guys I am using Hpple to get some data from the web and display it in a table view. I am using the code from ray wenderlich. The source code is available at the bottom of this page http://www.raywenderlich.com/14172/how-to-parse-html-on-ios. Then this is the website I am using to get the data http://ueat.site88.net/output.xml. And here is my xPathQuery

//day[@name='monday']/meal[@name='LUNCH']/counter[@name='Entrée']/dish/name. 

It gets the info if I NSLog what should go in the table view

Tutorial *thisTutorial = [_objects objectAtIndex:indexPath.row];
NSLog(@"%@", thisTutorial.title);
cell.textLabel.text = thisTutorial.title;

but then it doesn't appear in the table view, I know the nodes are not nil.

Heres the code for where it display the data

#import "MasterViewController.h"

#import "DetailViewController.h"

#import "TFHpple.h"
#import "Tutorial.h"
#import "Contributor.h"

@interface MasterViewController () {
    NSMutableArray *_objects;
    NSMutableArray *_contributors;
}
@end

@implementation MasterViewController

@synthesize detailViewController = _detailViewController;

Thanks for your help in advance

Answer 1

Your problem is simply that your first element contains new line characters. If you strip these out -

tutorial.title = [[[element firstChild] content]stringByReplacingOccurrencesOfString:@"\n" withString:@""];

then the table rows display correctly.
