用SwiftyXMLParser Alamofire解析XML

import Alamofire
import SwiftyXMLParser

func fetchAndParseXML() {
    let url = "https://example.com/data.xml"
    
    AF.request(url).responseData { response in
        switch response.result {
        case .success(let data):
            if let xml = XMLParser(data: data) {
                let parser = XMLParserDelegate()
                parser.parseXML(xml: xml)
                // 处理解析后的数据
                print(parser.parsedData)
            }
        case .failure(let error):
            print("Error fetching data: \(error)")
        }
    }
}

class XMLParserDelegate: NSObject, XMLParserDelegate {
    var parsedData: [String: Any] = [:]
    var currentElement: String = ""
    var currentKey: String = ""
    var currentValue: String = ""
    
    func parser(_ parser: XMLParser, didStartElement elementName: String, namespaceURI: String?, qualifiedName qName: String?, attributes attributeDict: [String : String] = [:]) {
        currentElement = elementName
        currentKey = ""
        currentValue = ""
    }
    
    func parser(_ parser: XMLParser, foundCharacters string: String) {
        currentValue += string
    }
    
    func parser(_ parser: XMLParser, didEndElement elementName: String, namespaceURI: String?, qualifiedName qName: String?) {

        }
    }
}

let xml = XMLParser(data: data, encoding: .utf8)
