Regular Expression

[Chris Kennedy]

Does anyone know a regular expression that will validate the file extension
but also allow multiple file extensions if necessary. It also needs to be
case insensitive. Regards, Chris.

 

[Kevin Spencer]

Defne "validate the file extension."
Define "allow multiple file extensions."

IOW, your question can't be answered as you have asked it. Regular
Expressions look for patterns of characters. You haven't defined any sort of
pattern to look for.
