Lua match regex

["Pete Kay" <petedao@...>]

Hi,

 

I am struggling with trying to match regex agains string.  Let's say I have a reg that looks like 4|44|22|445, basically a bunch of arbitrary numbers.  Is that any Lua function that can tell me if a string match exactly one of those numbers?

 

Any suggestion will be great.

 

Thanks,
Pete
