Post the idea, I would suggest.

I have exactly that custom transformer. Unfortunately I'm not allowed to post CT developed on company time, but it's a fairly straight forward PythonCaller. Get the list name, get the index, loop though the list (starting at i) replacing the attribute of list{i} with list{i+1}, remove list{-1}. The only "gotcha" is the behaviour of complex lists. Do you remove only the subcomponent, without reindexing, or do you remove all the related lists for that index, and reindex all of them.

Hi @bradr, the ListElementFilter from the FME Hub might help you to keep or remove elements that match a specific condition.

 

Tanks @takashi, the ListElementFilter does the job!
