使用Swift实现iOS App中解析XML格式数据的教程

public convenience init?(contentsOfURL url: NSURL)

NSXMLParser.parse() -> Bool

NSXMLParserDelegate.parser(parser: NSXMLParser, didStartElement elementName: String, namespaceURI: String?, qualifiedName qName: String?, attributes attributeDict: [String : String])

NSXMLParserDelegate.parser(parser: NSXMLParser, foundCharacters string: String)

class ViewController: UIViewController,NSXMLParserDelegate{
    override func viewDidLoad() {
        super.viewDidLoad()
        let parser = NSXMLParser(contentsOfURL: NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("data", ofType: "xml")!))
        //1
        parser!.delegate = self
        parser!.parse()
    }

 

    var currentNodeName:String!
    func parser(parser: NSXMLParser, didStartElement elementName: String, namespaceURI: String?, qualifiedName qName: String?, attributes attributeDict: [String : String]) {
        currentNodeName = elementName
        if elementName == "student"{
            if let id = attributeDict["id"]{
            print("id:\(id)")
            }
        }
    }

    func parser(parser: NSXMLParser, foundCharacters string: String) {
        //2
        let str = string.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceAndNewlineCharacterSet())
        if str != "" {
            print("\(currentNodeName):\(str)")
        }
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

func parser(parser: NSXMLParser, foundCharacters string: String) {
       print("\(string):\(str)")
 }
