Filtering different Revit Categories out of the same list

Hi all,

I hope someone can help me with this. I am fairly new to Dynamo and am trying to filter out certain Revit items from the same list. In the image below you can see that I have “Model Curves” and “Walls” in the same list… I am trying to isolate just the wall elements into their own list, is there a way to do this?
I have tried a bunch of “Contains” nodes but the Revit walls are not stored as strings as far as I can understand, so the nodes just return false for everything.
I hope someone can offer some advice or direction on what I need to do here. Help would be greatly appreciated!
Thank you.

Try this:


in my german version “Wände” means “walls”
