I am using Retrofit with simpleXMLConverter to get data out of an xml and use it in my android application. However, I am unable to bind the value of a certain tag on my value in my class. In my situation, I'm trying to bind the mtc:gas_type to my price variable in the Gasoline Class. I did manage to bind a value from a simple XML I found online with just 2 tags so it means I'm doing something wrong with this particular XML...

Error(Which means it can't find the tag):

java.lang.RuntimeException: org.simpleframework.xml.core.ValueRequiredException: Unable to satisfy @org.simpleframework.xml.Element(data=false, name=mtc:gas_type, required=true, type=void) on field 'price' private double com.example.alexander.ridy.Model.domain.Gasoline.price for class com.example.alexander.ridy.Model.domain.Gasoline at line -1

XML:

https://www.globalpetrolprices.com/api/getGasXML_weekly.php?gasoline_diesel=2&rate=EUR&countries=183&p=c5ab37e86d514beadb60d3d3d682f363

Endpoint interface:

interface Endpoint {

@GET("/api/getGasXML_weekly.php?gasoline_diesel=2&rate=LC&countries=183&p=c5ab37e86d514beadb60d3d3d682f363")
fun getDiesel(): Call<Gasoline>

@GET("/api/getGasXML_weekly.php?gasoline_diesel=1&rate=LC&countries=183&p=c5ab37e86d514beadb60d3d3d682f363")
fun getSuper95(): Call<Gasoline>

@GET("/api/getGasXML_weekly.php?gasoline_diesel=3&rate=LC&countries=183&p=c5ab37e86d514beadb60d3d3d682f363")
fun getLPG(): Call<Gasoline>

RetrofitClientInstance:

class RetrofitClientInstance {

private var retrofit: Retrofit? = null
private val BASE_URL = "https://www.globalpetrolprices.com"

fun getRetrofitInstance(): Retrofit? {
        retrofit = retrofit2.Retrofit.Builder()
            .baseUrl(BASE_URL)
            .addConverterFactory(create())
            .build()
    return retrofit
}

Gasoline Class:

@Root(strict = false) class Gasoline {

@field:Element(name="mtc:gas_type")
var price : Double = 0.0

lateinit var gasolineType : GasolineType

constructor()

The call:

    fun determineGasolineType() {
    val mySpinner = view?.findViewById(R.id.gasolineSpinner) as Spinner
    val text = mySpinner.selectedItem.toString()
    val service = RetrofitClientInstance().getRetrofitInstance()!!.create(Endpoint::class.java!!)
    lateinit var call : Call<Gasoline>
    lateinit var resp : Response<Gasoline>

    Thread({
        resp = service.getDiesel().execute()
        Log.d("",resp.body().toString())
    }).start()
