How to ignore unknown elements?

[Kryomancer]

I have a large, sprawling XML file but I'm only interested in certain tags, is there any way to avoid having to write a class or property for every single one and simply ignore anything that doesn't have a matching field on the Kotlin side of things? I do not need this to support serializing back into the original in any way,

Yes there is:

When you create the format implementation you can configure it with a policy:

XML {
    defaultPolicy {
        pedantic = false
        ignoreUnknownChildren() // or ignoreNamespaces() if only tags in other namespaces are to be ignored
    }
}

// alternatively you can set unknownChildHandler explicitly to any value you want.
