string for text that matches a
regular_expression, then replaces the matching text with
Regular expressions is a powerful language for matching patterns of partial words, whole words, or even multiple words. While basic regular expressions are straightforward to use, you can create complex expressions that are powerful but may be difficult to predict and debug --- and may be difficult for other people in your organization to understand.
So the best practice is: start with the basics, and add complexity only if you have no other choice.

An inventory attribute or formula column that returns a string.
