How can I map the first word or a specific portion of a xml? about xmlmapper HOT 1 CLOSED

class FirstWordTransform: XMLTransformType {
    typealias Object = String
    typealias XML = String
    
    func transformFromXML(_ value: Any?) -> Object? {
        if let stringValue = value as? String {
            return stringValue.components(separatedBy: " ").first
        }
        return nil
    }
    
    func transformToXML(_ value: Object?) -> XML? {
        // If you don't want το discard the rest of the string value in the serialization process,
        // you can probably keep it in a variable inside this XMLTransformType's instance AND
        // keep this XMLTransformType's instance inside Reponse class instance.
        // (although this will not be so pretty)
        return value
    }
}

class Response: XMLMappable {
    var nodeName: String!
    
    var foodFirstWord: String?
    
    required init(map: XMLMap) {
        
    }
    
    func mapping(map: XMLMap) {
        foodFirstWord <- (map["food"], FirstWordTransform())
    }
