Hi,

You can use the Index function like this:

If index starting from end is 0 that means that is found.

Hope this can help.

Hi Ankita,

Try this Regex Expression

[a-zA-Z0-9](.*[a-zA-Z0-9])?$

Let me know if it works for you.

Hi Ankita,

You can use the Regex_Replace server action available in the Text Extension for the mentioned use case.

See this sample app - RegexDemo (RWA)

The implementation also works in case of string ending with multiple dot and comma symbol

Used Regex Pattern:

"[,.]+$"

Hope this helps you!

Hi Ankita,

For future reference, there is a component called Regex How To that allows you to test regular expressions, see how to implement Regex both on Server side and Client side and see the most common patterns.

Using the same pattern as described by Benjith:

"[,.]+$"

you can see how it works both on Server side and Client side.

If you are developing a Mobile or Reactive application, you probably want to use a client action so it can work offline and it is more performant as it avoids going to the server.

Hope it helps.

Cheers,

I understand coming up with great solutions, but why not just keep it simple? That typically works best.

Var2 = Substr(Var1,Length(Var1)-1,1)

Var1 = If(Var2 = "." or Var2 = ",", Substr(Var1, 0, Length(Var1)-1), Var1)
