Я пытаюсь проанализировать эту страницу (http://www.tribunacampeche.com) с NSXMLParser, но когда я помещаю этот URL (http://www.tribunacampeche.com/index.php?format=feed&type=rss) в метод разбора, он ничего не возвращает. Если я пытаюсь с другими URL, такими как "http://www.hello.com/hello.xml", это работает.
Что я делаю не так, каков правильный URL для разбора этой страницы?
Спасибо
это код, который я использовал:
@implementation RootViewController
#pragma mark -
#pragma mark View lifecycle
- (void)viewDidLoad {
[super viewDidLoad];
self.title = @"Portada";
NSURL *aURL = [[NSURL alloc] initWithString:@"http://www.tribunacampeche.com/index.php?format=feed&type=rss"];
NSError *error = nil;
NSStringEncoding encoding;
NSString * path = [[NSString alloc] initWithContentsOfURL:aURL usedEncoding:&encoding error:&error];
/*
NSString *path = @"http://www.tribunacampeche.com/index.php?format=feed&type=rss";
*/
[self parseXMLFileAtURL:path];
NSLog(@"%@",path);
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
}
- (void)parseXMLFileAtURL:(NSString *)URL {
// inizializziamo la lista degli elementi
elencoFeed = [[NSMutableArray alloc] init];
// dobbiamo convertire la stringa "URL" in un elemento "NSURL"
NSURL *xmlURL = [NSURL URLWithString:URL];
// inizializziamo il nostro parser XML
rssParser = [[NSXMLParser alloc] initWithContentsOfURL:xmlURL];
[rssParser setDelegate:self];
// settiamo alcune proprietà
[rssParser setShouldProcessNamespaces:NO];
[rssParser setShouldReportNamespacePrefixes:NO];
[rssParser setShouldResolveExternalEntities:NO];
// avviamo il parsing del feed RSS
[rssParser parse];
}
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
currentElement = [elementName copy];
if ([elementName isEqualToString:@"item"]) {
// inizializza tutti gli elementi
item = [[NSMutableDictionary alloc] init];
currentTitle = [[NSMutableString alloc] init];
currentDate = [[NSMutableString alloc] init];
currentSummary = [[NSMutableString alloc] init];
currentLink = [[NSMutableString alloc] init];
}
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{
if ([elementName isEqualToString:@"item"]) {
/* salva tutte le proprietà del feed letto nell'elemento "item", per
poi inserirlo nell'array "elencoFeed" */
[item setObject:currentTitle forKey:@"title"];
[item setObject:currentLink forKey:@"link"];
[item setObject:currentSummary forKey:@"summary"];
[item setObject:currentDate forKey:@"date"];
[elencoFeed addObject:[item copy]];
}
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{;
// salva i caratteri per l'elemento corrente
if ([currentElement isEqualToString:@"title"]){
[currentTitle appendString:string];
} else if ([currentElement isEqualToString:@"link"]) {
[currentLink appendString:string];
} else if ([currentElement isEqualToString:@"description"]) {
[currentSummary appendString:string];
} else if ([currentElement isEqualToString:@"pubDate"]) {
[currentDate appendString:string];
}
}
- (void) parserDidEndDocument:(NSXMLParser *)parser {
[self.tableView reloadData];
}
