Although RegEx is powerful, I have tried using it once and found that coding my own CLR function to manipulate strings to what I want was 100 times faster than the RegEx function was.
If you are running the code against a small dataset this should not matter however I was running the code against millions of rows and this had a major impact on performance.

What did your custom CLR do to beat Regex so soundly?

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
