Me again. 
I was trying to use the custom nodes Get Tagged Element Id and Isolate in View, but I keep getting null values. My guess is that something needs to change or be updated in the Python Script in order for this to work, but I’m not sure because I am not getting any errors. Any advice, tips or ideas?
Thank you,
Rob K.
Both of these node were deprecated. They are no longer supported in newer Dynamo versions. Maybe one day they will get resurrected. For now you will just have to do without them.
Yes, its the Python code that is outdated. These nodes were made with 6.3 version and Dynamo completely changed how libraries are referenced in Dynamo 0.7.5 and onwards.
Bummer, thanks Konrad.
I guess users should beware of incorporating them into workflows unless they know Python and the Revit API.
Thanks again though.

Hi Rob, was dealing with the same issue and just found this code that seems to be working. Hope this helps.
These two nodes were now added back to Archi-lab package and will be supported from now on. Thank you for your patience.
