Using a variable in path to a node

Hi,

Is it possible to use a value stored in a node to define the path to another?

E.g.: I have a tree entity with an attribute "stand_number" (=1) (/plot/trees/stand_number (trees is a multiple entity)).

Can I use the value stored in "stand_number" to access /plot/dgm/dgm1m by substituting 1 in /plot/dgm/dgm1m? dgm1m is the basal area weighted mean diameter on stand 1.

The idea is to get the tree which is closest to dgm.

Thanks!

Hi András,
There isn't any way to generate a path dynamically like you are asking.
However you can use the stand_number inside the Apply when condition and use different variables in the Expression field. I hope this will help you.
Thanks,
