如何在swift3 XMLParse中使用urlsession

import Foundation
import XMLParser

let session = URLSession.shared
session.delegate = self

let url = URL(string: "https://example.com/xmlfile.xml")

let task = session.dataTask(with: url!) { (data, response, error) in
    if let error = error {
        print("Error: \(error)")
    } else if let data = data {
        // 在这里进行XML解析
    }
}

extension YourViewController: URLSessionDelegate, XMLParserDelegate {
    // 解析XML的开始标签
    func parser(_ parser: XMLParser, didStartElement elementName: String, namespaceURI: String?, qualifiedName qName: String?, attributes attributeDict: [String : String] = [:]) {
        // 处理开始标签
    }
    
    // 解析XML的结束标签
    func parser(_ parser: XMLParser, didEndElement elementName: String, namespaceURI: String?, qualifiedName qName: String?) {
        // 处理结束标签
    }
    
    // 解析XML的字符数据
    func parser(_ parser: XMLParser, foundCharacters string: String) {
        // 处理字符数据
    }
    
    // 解析XML的错误处理
    func parser(_ parser: XMLParser, parseErrorOccurred parseError: Error) {
        print("XML Parse Error: \(parseError)")
    }
}

task.resume()
