How can you get the value from a Managed Metadata Field?

[#1]

I'm trying to get the value from a managed metadata field for some custom validation rules. From another post (How do you validate Managed Metadata Field in a Nintex Form ), it seems that the operation isn't supported by Nintex right now, and the suggestions were that they use custom JavaScript. My problem is that I can't use custom JavaScript as this needs to be something that the average user can replicate. Does anyone have any suggestions for working around this?

For now, I am doing the following in a workflow:

Regular Expression

Get Item From Collection

Use my variable where needed.  I hope this helps.  If you find a quicker way, please let me know.
