List and Rename Rooms

Just fishing for some direction here… I tried the search and the results where quiet not what I was looking for. This is easily done using a Roomlist in Revit, however i am interested in exploring Dynamo and learn it bit by bit.
So, here it is:
I would like to list rooms, then filter the rooms to get only rooms with a specific name, and then rename it.

How do I go about it?
I have gotten only so far…

Cheers and thanks for all your tipps…

The list filter’s mask input wants a boolean or a series of trues and falses and it’ll filter your list based on those true false values. I’ve highlighted two ways to filter the room names, one method the room name has to contain some of the name we input and the other method the room name MUST equal it.
Hope this helps!
