Swift开发：解析xml文件案例

swift 代码：

<span style="font-size:24px;"> @IBAction func readxml(sender: AnyObject) {
        
        let parser = NSXMLParser(contentsOfURL: NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("data",ofType: "xml")!))
        
        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
        
        /* 提取属性 */
        if elementName == "person" {
            let age: String! = attributeDict["age"]
            print("currentNodeName:\(currentNodeName) age:\(age)")
        }
    }
    
    func parser(parser: NSXMLParser,foundCharacters string: String) {
        
        let str = string.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceAndNewlineCharacterSet())
        
        if str != "" {// 提取数据
            print("current node:\(currentNodeName),value: \(str)")
        }
    }
</span>
