dynamic tag name code broke

[NikkyAI]

used something based on https://github.com/pdvrieze/xmlutil/blob/master/examples/DYNAMIC_TAG_NAMES.md for a while, but the code in there does not work anymore

Exception in thread "main" nl.adaptivity.xmlutil.serialization.XmlParsingException: Invalid XML value at position: null: local name "Test_123" does not match expected "TestElement" (4:14)

this broke with the update t0 0.9.2 (and i have been dragging my feet to update)
how do we apprach this now?

example snippets (no control over the input XML sadly)

<LibraryClosedSections>
    <Section_3 Value="&gt;! Transition"/>
    <Section_6 Value="&gt;Fractal"/>
</LibraryClosedSections>

<QueueWindows>
	<Queue1 properties=""...>
        <Presets>
            <Preset Name="foo"/>
            <Preset Name="bar"/>
        </Presets>
     </Queue1>

	<Queue2 properties=""...>
        <Presets>
            <Preset Name="foo"/>
            <Preset Name="bar"/>
        </Presets>
     </Queue2>
</QueueWindows>

and we want to parse this into a structure like this (although if implementation forces a slightly different structure on us we can live with it)

@Serializable(with = LibraryClosedSectionsSerializer::class)
data class LibraryClosedSections(
    val sections: List<LibraryClosedSection>
) {
    @Serializable
    data class LibraryClosedSection(
        val index: Int,
        @XmlSerialName("Value")
        val value: String
    )
}

@Serializable(with = QueueWindowsSerializer::class)
data class QueueWindows(
    val queues: List<Queue>
) {
    @Serializable
    data class Queue(
        val index: Int,
        @SerialName("Name")
        val name: String,
        // additional attributes omitted for brevity.. its just more of the same
        @XmlElement
        @SerialName("Presets")
        val presetsContainer: Presets,
    ) {
        val presets get() = presetsContainer.presets
        @Serializable
        data class Presets(
            @XmlElement
            @SerialName("Presets")
            val presets: List<Preset>,
        ) {
            @Serializable
            @XmlSerialName("Preset")
            data class Preset(
                @SerialName("Name")
                val name: String,
                @SerialName("Id")
                val id: Int,
                @SerialName("Type")
                val type: String? = null,
                @SerialName("Comments")
                val comments: String? = null,
                // additional attributes omitted for brevity.. its just more of the same
            )
        }
    }
}

this now breaks with

Invalid XML value at position: null: local name "Section_3" does not match expected "LibraryClosedSection" (1:925)

how do we approach this kind of (awful) XML?
.. and i hope the dynamic tagname example can be updated

[pdvrieze]

I've just updated the example (also in master), and added a unit test (so it doesn't just break unnoticed). There were some underlying fixes/changes in the parser that the dynamic reader was not updated to handle. I've also updated the code to use the new XmlSerializer interface (that extends KSerializer) – this interface makes xml specific serialization easier.
