Parsing XML but got errors

Question

So I am attempting to Parse a RSS feed using TFHpple parser. Here is the code in question:
// AriesView.m
// Horoscopes
// Created by DJB on 9/2/10.
// Copyright 2010 _MyCompanyName_. All rights reserved.
#import "AriesView.h"
@implementation AriesView
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
NSString *data = [NSString stringWithContentsOfURL:[NSURL URLWithString: @"feed://www.findyourfate.com/rss/dailyhoroscope-feed.asp?sign=Aries"] encoding:NSUTF8StringEncoding error:NULL];
NSData *htmlData = [data dataUsingEncoding:NSUTF8StringEncoding];
TFHpple *xpathParser = [[TFHpple alloc] initWithHTMLData:htmlData];
NSArray *elements = [xpathParser search:@"/item/description"];
NSLog( @"%@", elements);
TFHppleElement *element = [elements objectAtIndex:0];
NSString *paragraph = [element content];
NSLog(@"%@", paragraph);
summary.text = paragraph;
[xpathParser release];
[htmlData release];
When I run the program and click on the button that bring me to this view, the app crashes. When looking at the Debug log, this is what it says:
[Session started at 2010-09-04 14:16:32 -0400.]

What am I doing wrong? How can I fix the problem?

Answer 1

I changed my code around and got the information that I wanted parsed. Now, however, when I run the app, and click on a button that I made to reload the data, the app crashes. I have also placed two NSLogs that show that they both receive the data that I want. My problem now, is that even though paragraph has the correct data in it, it won't output the data into the UILabel *summary. Any ideas?
-(IBAction)reloadInfo:(id)sender {
if (sender == reload) {
NSString *data = [NSString stringWithContentsOfURL:[NSURL URLWithString: @"http://www.astrology-enterprises.com/show_HOROSCOPES.asp?SIGN=ARIES&VIEW=0"] encoding:NSUTF8StringEncoding error:NULL];
NSData *htmlData = [data dataUsingEncoding:NSUTF8StringEncoding];
TFHpple *xpathParser = [[TFHpple alloc] initWithHTMLData:htmlData];
NSArray *elements = [xpathParser search:@"//html//body//span"];
NSLog(@"%@", elements);
TFHppleElement *element = [elements objectAtIndex:0];
NSString *paragraph = [element content];
NSLog(@"%@", paragraph);
summary.text = paragraph;
[xpathParser release];
[htmlData release];
