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.
