XCode, iOS: Parsing HTML encoding with hpple - html

Question

I have a problem with encoding when parsing web page with hpple in XCode.
- (void)loadTutorials {
NSURL *tutorialsUrl = [NSURL URLWithString:#"http://qrz.si/members/s55db/"];
NSData *tutorialsHtmlData = [NSData dataWithContentsOfURL:tutorialsUrl options:NSASCIIStringEncoding error:nil];
TFHpple *tutorialsParser = [TFHpple hppleWithHTMLData:tutorialsHtmlData];
NSString *tutorialsXpathQueryString = #"//td[#class='data']";
NSArray *tutorialsNodes = [tutorialsParsersearchWithXPathQuery:tutorialsXpathQueryString];
NSMutableArray *newTutorials = [[NSMutableArray alloc] initWithCapacity:0];
for (TFHppleElement *element in tutorialsNodes) {
Tutorial *tutorial = [[Tutorial alloc] init];
[newTutorials addObject:tutorial];
for (TFHppleElement *child in element.children) {
if ([child.tagName isEqualToString:#"img"]) {
// NSLog([child objectForKey:#"src"]);
} else if ([child.tagName isEqualToString:#"p"]) {
//NSLog([[child firstChild] content]);
tutorial.title = [[child firstChild] content];
}
}
}
_objects = newTutorials;
[self.tableView reloadData];
}
Page should be UTF-8 as the source points out, but I get wierd characters out.
How can I force change encoding of the data? Any help would be highly appreciated!

Answer 1

options:NSASCIIStringEncoding
is useless here, documentation points out that it's not the right way to go.
To set encoding, one must edit XPathQuery.m by Matt Gallagher, that I got in the same tutorial. Changes were visible, but nothing worked, as the site was clearly UTF-8 encoded.
The problems were server side and administrator offered me good old plain XML :)

Answer 2

You are telling NSData object that the contents of the URL you are loading is ASCII not UTF8:
NSData *tutorialsHtmlData = [NSData dataWithContentsOfURL:tutorialsUrl options:NSASCIIStringEncoding error:nil];
Which should be
NSData *tutorialsHtmlData = [NSData dataWithContentsOfURL:tutorialsUrl options:NSUTF8StringEncoding error:nil];
