Is it possible to insert an element?

[zeroarst]

I am just coming from https://github.com/cretz/kastree as it points me to here.

Bascially what I want to do is to insert a new element. kastree can modify the node, but does not seem to be able to insert a node. So I came here and take a look. Loos like this library can only parse but cannot insert an element? https://github.com/kotlinx/ast/issues/43
