I think you can use the split tree with a mask of

{?;0,2,...}

Perfect.

Could you explain what each symbol means between brackets?

The semi-colons separate indices. So this mask only works for paths that look like {X;Y}

The question mark means any number is accepted in the first place. The '0,2,...' means that zero, two and every other even number is excepted in the second place.

Thanks David

I also downloaded your webinar video for data trees.

Hope that it would help me a lot. As the more, I use grasshopper, the bigger necessity I need to learn this difficult stuff.

Thanks again.
