Error when trying to parse an XML with Retrofit

  • 772

I'm trying to deserialize the response I receive from a service in XML format and I'm having problems since it tells me that the name is already repeated, but otherwise I don't know how I can do it... I'm sending you the error, the code and the XML which I need to deserialize.

org.simpleframework.xml.core.PersistenceException: Element 'channelLevel' is already used

<channels>
    <channelLevel ref="00000000-0000-1000-0000-000000000016">
        <id>001</id>
        <name>Max</name>
        <order>100</order>
        <country>MX</country>
    </channelLevel >
    <channelLevel refId="00000000-0000-1000-0000-000000000017">
        <id>001</id>
        <name>Max</name>
        <order>100</order>
        <country>MX</country>
    </channelLevel >
    <channelLevel refId="00000000-0000-1000-0000-000000000018">
        <id>001</id>
        <name>Max</name>
        <order>100</order>
        <country>MX</country>
    </channelLevel >
    <channelLevel refId="00000000-0000-1000-0000-000000000019">
        <id>001</id>
        <name>Max</name>
        <order>100</order>
        <country>MX</country>
    </channelLevel >
</channels>

@Root(name = "channels", strict = false)
data class ChannelsList(
    @field:ElementList(name = "channelLevel", required = false)
    var channelLevel: List<Channels>
)

@Root(name = "channelLevel", strict = false)
data class Channels(
    @field:Element(name = "id", required = false)
    var id: Int? = null,
    @field:Element(name = "name", required = false)
    var name: String? = null,
    @field:Element(name = "order", required = false)
    var order: Int? = null,
    @field:Element(name = "country", required = false)
    var country: String? = null,
)

    Your problem is not related to retrofit but to the serializer you are using. In its documentation it says that if elements don't have a wrapping parent, you should add inline=trueto the annotation.

    And you also need to add a default value to the propertychannelLevel

    @Root(name = "channels", strict = false)
data class ChannelsList(
    @field:ElementList(inline = true, required = false)
    var channelLevel: List<Channels> = arrayListOf()
)
