I found this from previous post: (.+)@(\w+)(\.\w+)*\.(\w{2,6})

Can someone explain what it means?

I don't see "\w" in IP, and have no idea about "{2,6}"

Thanks.

Hi Troy0118,
Excellent question. This is a regular expression. It is meant to map an e-mail address. The \w means word I think. Another example that matches e-mail address is: \b[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b. You can usehttp://www.regular-expressions.info/index.html as a reference.

Hi Patrick,
really helpful, thanks.

Hi,

I dont understand this, but I tried to put:

[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}

and

\b[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b

and

(\b[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b)

 In

Button properties

->Set condition

-> matches pattern

->custom pattern

But it prompts:

The pattern is not valid??? Why?

I have tried another 5 different email patterns (based on various blogs) but none of them work correctly, but this is first time the pattern is not even accepted.  http://www.regular-expressions.info/index.html Is too much for me. I only want to now what is the correct pattern for email. Please help me.

Hi Valtteri,

You can try this pattern. It covered 95 % all e-mail addresses that I can come up with.

([\w\-\.]+)@((\[([0-9]{1,3}\.){3}[0-9]{1,3}\])|(([\w\-]+\.)+)([a-zA-Z]{2,4}))

But it still needs a small bit of fixing as it allows.
