你好，我是 Swift 和 SOAP 的新手，我正在使用 http://www.webservicex.net/globalweather.asmx并得到响应作为 posts 我想将此 response 打印到 myTableViewController 请帮忙 谢谢
响应

{Country = ""GetCitiesByCountryResult = "<NEWDATASET><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>BHAIRAWA AIRPORT</CITY></TABLE><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>JUMLA</CITY></TABLE><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>KATHMANDU AIRPORT</CITY></TABLE><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>POKHARA AIRPORT</CITY></TABLE><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>SIMRA AIRPORT</CITY></TABLE><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>SURKHET</CITY></TABLE><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>TAPLEJUNG</CITY></TABLE><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>BIRATNAGAR AIRPORT</CITY></TABLE></NEWDATASET>";}

最佳答案

检查您的代码后，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 数据并再次解析它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 以获得进一步的结果

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()
}
