Anyone with experience using xml util <https github com pdvrieze xmlutil> know if it s possible to set my tag name and element text based on properties of my class More in thread

I have a model that more or less mimics the XML structure it gets serialized to e g ```data class Model name String = default text String = attributes Map lt String String gt = emptyMap children Collection lt Model gt = emptyList ``` Given an instance like this ```val model = Model name = parent attributes = mapOf attribute to value children = listOf Model name = child text = child text ``` The xml would look like ``` lt parent attribute= value gt lt child gt child text lt child gt lt parent gt ```

Is is possible to achieve this type of content based serialization with xmlutil

andyg · Answer

I have used xmlutil for a project recently but I am certainly not a definitive expert I believe it isn t impossible but may be quite difficult Starting point would be <https github com pdvrieze xmlutil blob master examples DYNAMIC TAG NAMES md|here> to see how some tag names and attributes too I assume can be created dynamically with a custom serializer If your element and attribute names are entirely dynamic this may the the only option however if you have a predetermined list of possible values like an enum creating a sealed class then classes for all the individual options with simple annotations may be a lot easier If you will also be de serializing you ll have to consider how to recognize the dynamic tag attribute names and then convert them to the generic `Model`

Good points all around I ve been reading through the dynamic tag names example and this use case seems to be quite difficult as you said Unfortunately there is not a predetermined set of possible values This particular model is meant to be extensible for application specific detail otherwise your enum + sealed type suggestion would be a good fit and I d get polymorphic serialization for free from xmlutil I recently stumbled on ` XmlOtherAttributes` which has helped significantly because it takes care of `Model attributes` `Model children` is handled inherently so it s just down to the dynamic names and text and I think `XmlDelegatingTagWriter` might be the only way
