REGEX Transformation in Rule Does Not Return Capture Group

I am trying to use the REGEX transform in a rule and instead of returning the match group is is returning the entire input string:

val newValue = transform(“REGEX”, “.=(\d.\d*).*”, “temp=1.2”)
if(db) logInfo(“EX_FoxnovaStrip”, “newValue = {}”, newValue

Prints

newValue = temp=1.2

Why doesn’t this return 1.2?

I just figured it out. I didn’t have the REGEX transformation add-on installed.:joy:
