检查完代码后，我发现您的问题是您没有正确解析XML数据。

获取“GetCitiesByCountryResult”的值后，您可以将其转换为xml数据并再次解析以获取所有城市的列表作为数组。之后，您可以将其传递给viewcontroller以获得更多结果

let xmlArray = posts.value(forKey: "GetCitiesByCountryResult") as! [String]
let xmlString: String = xmlArray[0]

if let xml_Data:Data = xmlString.data(using: String.Encoding.utf8) {
    parser = XMLParser(data: xml_Data)
    parser.delegate = self
    parser.parse()
}

我想打印soap响应myTableViewController
