okay here is yar solution... you released htmlData at the end. dont release it. cause you didn't alloc that...

NSData *htmlData = [NSData dataWithContentsOfURL:[NSURL URLWithString: @"http://www.objectgraph.com   /contact.html"]];
TFHpple *xpathParser = [[TFHpple alloc] initWithHTMLData:htmlData];     
NSArray *elements  = [xpathParser search:@"//h3"]; // get the page title
TFHppleElement *element = [elements objectAtIndex:0];
NSString *h3Tag = [element content];  
NSLog(@"Html tags :%@",h3Tag);
mLabel.text = h3Tag;
[xpathParser release];
