我试图解析，但只有“项”数据可以解析不是“标题” &“图像”

这里是我的代码...

 var parser = NSXMLParser() 
    var posts = NSMutableArray() 

    var elements = NSMutableDictionary() 

    var element = NSString() 
    var title1 = NSMutableString() 
    var title3 = NSMutableString() 
    var date = NSMutableString() 
    var link = NSMutableString() 
func beginParsing() 
    { 

     posts = [] 
     parser = NSXMLParser(contentsOfURL:(NSURL(string:"http://zeenews.india.com/rss/india-national-news.xml"))!)! 
     parser.delegate = self 
     parser.parse() 

     tbData!.reloadData() 
    } 
func parser(parser: NSXMLParser, didStartElement elementName: String, namespaceURI: String?, qualifiedName qName: String?,attributes attributeDict:[NSObject :AnyObject]) 
    { 
if (elementName as NSString).isEqualToString("title") 
     { 
     elements = NSMutableDictionary.alloc() 
      title3 = NSMutableString() 
      title3 = "" 
     } 

     if (elementName as NSString).isEqualToString("item") 
     { 
      elements = NSMutableDictionary.alloc() 
      elements = [:] 
      title1 = NSMutableString() 
      title1 = "" 
      date = NSMutableString() 
      date = "" 
      link = NSMutableString() 
      link = "" 
     } 
    } 

    func parser(parser: NSXMLParser, didEndElement elementName: String, namespaceURI: String?, qualifiedName qName: String?) 
    { 
if (elementName as NSString).isEqualToString("title") 
     { 
      if !title3.isEqual(nil) { 
       elements.setObject(title3, forKey: "title") 
       //posts.addObject(elements) 

     } 

     } 

     if (elementName as NSString).isEqualToString("item") { 
      if !title1.isEqual(nil) { 
       elements.setObject(title1, forKey: "title") 
      } 
      if !date.isEqual(nil) { 
       elements.setObject(date, forKey: "date") 
      } 
      if !link.isEqual(nil){ 
       elements.setObject(link, forKey: "link") 
      } 
      posts.addObject(elements) 
     } 
     //posts.addObject(elements) 
     //posts.addObject(post) 
    } 

    func parser(parser: NSXMLParser, foundCharacters string: String?) 
    { 
     if element.isEqualToString("title") 
     { 
     title3.appendString(string!) 
     } 


     if element.isEqualToString("title") { 
      title1.appendString(string!) 
     } 
     if element.isEqualToString("link"){ 
       link.appendString(string!) 
     } 

     if element.isEqualToString("pubDate") { 
      date.appendString(string!) 
     } 
    } 

Plz ...建议任何解决方案如何我可以解析整个rss feed数据...

Answer 1

我纯粹是猜测现在。

你说item解析得很好，而title和image没有。

望着XML似乎image例如只包含CDATA元素

<image> 
    <url>

我发现这里this post Stack Overflow上如果有人询问如何在XML处理CDATA。事实证明，NSXMLParserDelegate有一个名为可选方法：

parser(_ parser: NSXMLParser, foundCDATA CDATABlock: NSData)

您可以在Apples documentation

这里读到它或许可以帮助你吗？
