Syntax for findrx/replecerx

[stupomer]

Hi,
I would like to search a name string so that the degree is removed ", MD" or ", DDS" or ", PHD" or ", NP"

I think I can write the findrx regex string for those pretty easy -
but how do you set it up so that if it doesn't find the first one, it searches for the second one, if that fails, go to the third, etc.....
can it be setup to search for all four at once or do I have to do it serially with err statements?

Thanks so much!
Stuart
