I tried to parse but only "item" data can parse not the "title" & "image"

here is my code...

     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!)
        }
    }
