Question

我正在尝试使用NSXMLParser解析此页面（http://www.tribunacampeche.com），但是当我放入此URL时（http://www.tribunacampeche.com/index.php?format=feed&type= rss）在parse方法中它什么都不返回。如果我尝试使用像“http://www.hello.com/hello.xml”这样的其他网址，那就可以了。

我做错了，解析此页面的正确URL是什么？

由于

这是我使用的代码：

@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];
}

这是控制台返回的内容：

            input{-wap-input-format: "*m"; format: "*m"; }
        </style>

这个RSS的正确URL是什么？
