Expressions query?

DigPeter · January 30, 2014, 12:25:36 PM

I am using expressions such as: {File.Categories|filter:Subject;level:3}, for instance in the category A|B|C|D this would give C

Is it possible to designate an element counting from the bottom by using a negative number; that is {File.Categories|filter:Subject;level:-2}, again to give C? Or is there another method?

I thought that I had read this somewhere in the Help topics, but cannot find it. It would be useful, where the number of elements vary under a top node.

@Mario: If it is possible to arrange this, I will raise a feature request.

You can access the leaf, the root and all levels in-between using an index. There is no other way, and no negative index.

Thanks, Mario. Would it be possible to provide this?

Sure, someday. Add a feature request for it. I'm doing small changes all the time.

@Mario
Thanks for fixing that. I hope that other people might find it useful too.

OT I would be grateful if you take a quick look at https://www.photools.com/community/index.php?topic=1666.msg10597#msg10597 . Do you think you might be able to solve this problem in due course?

I keep an eye on all bugs. Currently I'm working in another area.

OK, thanks - as I said, in due course
