/ 13 марта 2011

Я пытаюсь проанализировать XML из RSS-канала.

Содержит данные ATOM, и я хотел бы проанализировать их с помощью библиотеки GData.

Код XML выглядит следующим образом: 

<item>
    <title>Madoka Kaname</title>
    <link>http://emperpep.deviantart.com/art/Madoka-Kaname-200775806</link>
    <guid isPermaLink="true">http://emperpep.deviantart.com/art/Madoka-Kaname-200775806</guid>

Я понятия не имею, как получить данные, содержащиеся в поле media: content.Может ли кто-нибудь помочь мне с этим?

Я нашел ответ.Вот код: 

NSArray *items = [channel elementsForName:@"item"];
    for (GDataXMLElement *item in items)
    {  
        NSString *articleTitle = [item valueForChild:@"title"];
        NSString *articleUrl = [item valueForChild:@"link"];            
        NSString *articleDateString = [item valueForChild:@"pubDate"]; 

        NSArray *mediaArray = [item elementsForName:@"media:content"]; //this is the code for what I needed
        for (GDataXMLElement *content in mediaArray)
        {
            NSString *url = [[content attributeForName:@"url"] stringValue];
            NSLog(@"URL: %@", url);
        }

        NSDate *articleDate = [NSDate dateFromInternetDateTimeString:articleDateString formatHint:DateFormatHintRFC822];

        RSSEntry *entry = [[[RSSEntry alloc] initWithBlogTitle:blogTitle 
                                                  articleTitle:articleTitle 
                                                    articleUrl:articleUrl 
                                                   articleDate:articleDate] autorelease];
        [entries addObject:entry];


    }
