Complex splitting data Tree - Automation

[interkinactive (Jess)]

Hi there,
i cant get any further at the moment.

I have a variable number of blocks which I insert with Elefront.
I managed to give every item on different layers their own branch.
Every block might have a different number of layers and elements per layer!

Now I need of every block just the first branch ({0;0;0}, {0;1;0} and {0;2;0}
I could go with explode tree, but the number of blocks might vary. I want do find an automation.

Any suggestions what trick would do? I hope my images and files are helpful

Thank you very much!
Jess

Your way is very interessting and I learned a lot analysing it.

Unfortunately it is not working. When I add another list item block to yours, there is some lines of block one, and one of block 3 chosen.
maybe my question was not clear enough…

Lets try it a bit more general:
I need to split the first branch of the tree (or the second) and need a way to do so. There will be more blocks than just 3!

Here is a pic which branches I need:

Thats the post what helped me:

Unable to filter multiple branches in data tree

Hey all, What I have: a data tree with two types of branches - they either start with a 1 or with a 0 - What I want: to retrieve all of the ones that start with a 1 or 0. How I used to do this: I would just use a tree branch panel and insert: {0;} or {1;} - and done! For some reason I’m unable get this done. Could anyone shed some light on the issue?
