I am trying to parse out the words within a string and trying to use regexp. I am open to using any functions or logic that will work.
Example: in one of the columns i have:

Variable1 =‘Y’ and variable3=5
Variable2 ne 2 and variable5 ne’A’

My output needs to capture all the variable word names before the delimiter =, ne
the variable names have a _ in it.

Appreciate any help. Thanks
