How can I map the first word or a specific portion of a xml?

[jeremiasdsa]

Hi @gcharita,

Is that possible to parse just the first word or the portion I want from the xml?
ex:
In this case I need just the first word, "Belgian" from food.

<Response> <food>Belgian Waffles</food> </Response>

You can pretty much do whatever you like in the mapping process by implementing your own custom XMLTransformType.

To map the first word of the food element's value, your can use:

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())
    }
}
