We are using @pxReplaceAllViaRegex function to replace multiple commas with a single comma.

@pxReplaceAllViaRegex(.ToString,"(,)\\1+",",")

Recently we got a production issue where our ToString property holds,

Proprietary information hidden, Proprietary information hidden,, ,,, Proprietary information hidden, Proprietary information hidden

After using this function value is returning like  Proprietary information hidden, Proprietary information hidden, , Proprietary information hidden, Proprietary information hidden 

Because of space between 2 commas mails were not sent to Proprietary information hidden, Proprietary information hidden user id's.

Any idea to resolve this space issue by using same function?

Thanks
