Swift parsing attribute name for given elementName -

here part of url

<cities>   <country name="Абхазия">     <city id="37188" region="27028" head="" type="3" country="Абхазия" part="" resort="" climate="">Новый Афон</city>     <city id="37178" region="10282" head="" type="3" country="Абхазия" part="" resort="" climate="">Пицунда</city>     <city id="37187" region="37187" head="" type="3" country="Абхазия" part="" resort="" climate="">Гудаута</city>     <city id="37172" region="10280" head="" type="3" country="Абхазия" part="" resort="" climate="">Гагра</city>     <city id="37189" region="10281" head="0" type="3" country="Абхазия" part="" resort="0" climate="">Сухум</city>   </country> 

user types name of city, example: "Пицунда" , want id. "Пицунда" id "10282".

below i've posted not-working code.

var parser: nsxmlparser! var city: string = string() var ifdirok = false var ifcitynameok = false   override func viewdidload() {     super.viewdidload()      let url: nsurl = nsurl(string: "https://pogoda.yandex.ru/static/cities.xml")!      parser = nsxmlparser(contentsofurl: url)     parser.delegate = self     parser.parse() }  override func didreceivememorywarning() {     super.didreceivememorywarning()     // dispose of resources can recreated. }    func parser(parser: nsxmlparser!, didstartelement elementname: string!, namespaceuri: string!, qualifiedname qname: string!, attributes attributedict: [nsobject : anyobject]!) {     //let cityid = attributedict ["id"] as? nsstring     if (elementname == "city"){         ifdirok = true     } }  func parser(parser: nsxmlparser!, foundcharacters string: string!) {     var data = string.stringbytrimmingcharactersinset(nscharacterset.whitespaceandnewlinecharacterset())     if (data == city){         ifcitynameok = true     } }  func parser(parser: nsxmlparser!, foundattributedeclarationwithname attributename: string!, forelement elementname: string!, type: string!, defaultvalue: string!) {     if (ifdirok && ifcitynameok){         println("\(attributename)")     } }  func parser(parser: nsxmlparser!, didendelement elementname: string!, namespaceuri: string!, qualifiedname qname: string!) { } 

after all, want pass id url file (export.yandex.ru/weather-ng/forecasts/{id of city}.xml) , parse it. need create swift class , somehow connect first one?

building dictionary of [city:id] can solution you. have implemented simple solution based on article lifecycle of nsxmlparser @ http://www.codeproject.com/articles/248883/objective-c-fundamentals-nsxmlparser .

following method called when when element starting. can retrieve city id attribute , save in instance level variable can use in next method.

func parser(parser: nsxmlparser, didstartelement elementname: string, namespaceuri: string?, qualifiedname qname: string?, attributes attributedict: [nsobject : anyobject])  

and then, following method called when parser see between starting , ending.

func parser(parser: nsxmlparser!, foundcharacters string: string!)  

so, can city name here. have city id , city name add new item [city:id] dictionary.

once build dictionary, searching simple.

here working test code.
