How do I get a list of values filtered by tags

Hi,

I have a list of tags inside webflow, the output looks likes this for every tag:

I managed to get all of those IDs into one array by using an Array Aggregator and then a Set Variable with {{map(142.array; “id”)}}.

That gives me a nice array with all the IDs.

I have a blog post that has tags - those tags are in an array called tags.

How can I filter out those IDs that do not belong to one of those post-tags? Or in other words: how do I get a list of those IDs that belong to my tags. The order is not important. I am a bit stuck here with the data-type handling. fieldData.name is where the name has to be the same as in tags-array.

I thought about iterating over those tags of my blog post, but that results in 3 Operations (3 tags in the array) and from there I am also stuck to get those back into one nice array/list.

So that is how the workflow looks like at the moment:

Best Regards
Denis
