Hi, and thanks for your input.
> RegExp by itself cannot do this. You have to match all parts of the input into different capturing groups, then use lower() combined with format() to build a new string. Putting the capturing groups into an array is the most useful option.
OK - I *_kind_* of see what you're saying.
There's a small fiddle here (https://dbfiddle.uk/rhw1AdBY) if you'd care to give an outline of the solution that you propose.
Thanks again,
E.
