    RegEx is always tough to digest (without referring to document), so it would be good to give an explanation of the logic.

    I'm not sure whether or not you meant this to be a separate post or a post on some other thread, but I absolutely agree.

    I'll also state that RegEx, especially RegEx Replace, is frequently a whole lot slower than normal T-SQL if it can, indeed, be done in T-SQL.  Several of us had a bunch of races on a rather larger thread here on SQLServerCentral. com that proved it.  Since this site has gone through two "improvement" upgrades since then, I've lost track of a working URL to get back to it and I'm loath to search for it.
