# Can I check the next to last item in a list of items?

Asked by Andras on 2014-10-09

Hi!

I would like to check some of the attributes of the next to last item of a list of items, e.g. recorded trees. How do I do that?

Thanks!

Suppose that you have a calculated attribute **tree_num** inside the "tree" entity using this expression: **idm:position()**; then you can select the trees from next to last item with an expression similar to this (valid for attributes defined inside the "tree" entity): **parent()/tree[tree_num > $this/parent()/tree_num]**. The expression **$this/parent()/tree_num** is used to reference the tree_num of the tree into which the attribute is defined.
Thanks.
