Question

Hi
I like to build a string function:

if member of a list of string: 
    "Nissan" from "Honda, Toyota, Nissan, Mazda"

  if start with or end with
    "Nissan" from "Nis*" as start with 
    "Nissan" from "*san" as end with

  if not start with or end with 
    "Ford" from "^Nis*" as start with 
    "Ford" from "^*san" as end with 

  if Not member of a list of string:
    "Ford" from "^Hon*, ^Toy*, Nis*, Mazda"

I was thinking Regex maybe the solution, but how I implement it?

Thank you
Wes

Difficult to understand what you are asking for, but I will do my best to guess:

1. To check if string is one of the following: Honda, Toyota, Nissan, Mazda

   ^(Honda|Toyota|Nissan|Mazda)$

2. Starts with Nis

   ^Nis.*$
   

3. Ends with san

   ^.*san$
   

4. Not starts with Nis

   ^(?!Nis).*
   

5. Not ends with san

   ^.*(?<!san)$
   

6. Does not contain any of Hon*, Toy*, Nis*, Mazda

   ^(?!Hon.*|Toy.*|Nis.*|Mazda).*
