compare 2 lists with a transformer

Hi!

Does it exist an easy way (1 transformer) to compare 2 lists from differents dataset ?

For example :

dataset 1 - feature 1

list{0}.NAME = A

list{1}.NAME = B

dataset 2 - feature 1

list{0}.NAME = B

list{1}.NAME = C

I would like to have the difference so here :

=>on the dataset1, feature1 “A” is missing

=>on the dataset2, feature1 “C” is missing

the index of the value doesn’t matter, juste the presence of the value is important.

I succed with 2 ListExploder and 1 FeatureMerger, and I imagine It would be working too with  ListExploder, FeatureMerger and ListSearcher, but maybe it exist a transformer to do that more quickly.

Thanks!
