is there an easy way to do xml serialization in kotlinjs?

<https://developer.mozilla.org/en-US/docs/Web/API/XMLSerializer>

Yes, but that seems to only be able to use Nodes. What if I want to serialize any data classes?

You cannot do that now, you actually need not a xml serialization, but xml mapper for data classes.
I’m pretty sure you can implement own xml steriliser with kotlinx.serialization it would be a nice contribution.
