Hpple not able to parse HTML - ios

Question

I'm using Hpple to parse HTML and it seems that it doesn't recognize it is actually XML, which it should (XCode debugger shows this variable isXML = (BOOL) NO and it doesn't collect any data). How do I fix this?
This is my code (they're may be other bugs as well). the parse method/function is called first with [ListParser parse:#"http://www.fanfiction.net/book/Harry-Potter/" at:#"//div[#=\"class\"]"];:
#interface ListParser () //private
+ (NSArray*) getNodeListAt: (NSURL*) page inside: (NSString*) page;
+ (NSDictionary*) getNodeData: (TFHppleElement*) node;
+ (void) addMiniListData: (NSString*) list to: (NSMutableDictionary*) dict;
#end
#implementation ListParser
+ (NSArray*) getNodeListAt: (NSURL*) page inside: (NSString*) path { // "//div[#class"z-list"]"
NSData *data = [NSData dataWithContentsOfURL: page];
TFHpple *listparser = [TFHpple hppleWithHTMLData:data]; //WHERE CODE SEEMS TO STOP TO WORK
NSArray *done = [listparser searchWithXPathQuery: path];
return done;
}
+ (void) addMiniListData: (NSString*) list to: (NSMutableDictionary*) dict{
NSArray *parts = [list componentsSeparatedByString:#" - "];
for(NSString* p in parts){
NSArray* two = [p componentsSeparatedByString:#": "];
[dict setObject:[two objectAtIndex:1] forKey:[two objectAtIndex:0]];
}
}
+ (NSDictionary*) getNodeData: (TFHppleElement*) node{
NSMutableDictionary* data = [NSMutableDictionary dictionary];
[data setObject:[[[node firstChild] firstChild] objectForKey:#"href"] forKey:#"Image"];
[data setObject:[[node firstChild] text] forKey:#"Title"];
[data setObject:[[[[node firstChild] children] objectAtIndex:2] text] forKey:#"By"];
[data setObject:[[[[node firstChild] childrenWithClassName:#"z-indent"] objectAtIndex:0] text] forKey:#"Summery"];
[self addMiniListData:[[[[[[node firstChild] childrenWithClassName:#"z-indent"] objectAtIndex:0] childrenWithClassName:#"z-padtop2"] objectAtIndex:0] text] to: data];
return data;
}
+(NSArray*) parse: (NSString*) address at: (NSString*) path{
NSURL *url = [[NSURL alloc] initWithString:address];
NSArray* list = [self getNodeListAt:url inside:path];
NSMutableArray *data = [[NSMutableArray alloc] init];
for (TFHppleElement* e in list) {
[data addObject:[self getNodeData:e]];
}
return [[NSArray alloc] initWithArray: data];
}
#end

If you need to parse XML with a TFHpple, you should tell it that you're doing so. You're calling +hppleWithHTMLData:. If you read the implementation of this method, you will see that it sets isXML to NO. Instead, use the hppleWithXMLData: method.
