WTF:

```
str = "removed_email_address@domain.invalid, removed_email_address@domain.invalid, removed_email_address@domain.invalid"

emails_array = Array.new
emails = str.split(",")
emails.each do |single_str|

  tmp = single_str[/^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/i]

  if !tmp.nil?
    emails_array << tmp

  end
 end

```

— Expected result

emails\_array =\> [“removed\_email\_address@domain.invalid”,“removed\_email\_address@domain.invalid”,“removed\_email\_address@domain.invalid”]

-----Actual result

emails\_array =\> [removed\_email\_address@domain.invalid]

Can’t understand

There’s a space after each comma in str that the regexp does not  
allow. Either remove them or split by /\s\*,\s\*/.

I get:

[“removed\_email\_address@domain.invalid”, " removed\_email\_address@domain.invalid", " removed\_email\_address@domain.invalid"]

“removed\_email\_address@domain.invalid, removed\_email\_address@domain.invalid, removed\_email\_address@domain.invalid”.split(’,’)  
=\> [“removed\_email\_address@domain.invalid”, " removed\_email\_address@domain.invalid", " removed\_email\_address@domain.invalid"]

Notice the white space at the start of all but the first email address.

With that whitespace there, the /^ in your regex won’t be satisfied.

You probably want do split more like this:  
“removed\_email\_address@domain.invalid, removed\_email\_address@domain.invalid, removed\_email\_address@domain.invalid”.split(/\s\*,\s\*/)  
=\> [“removed\_email\_address@domain.invalid”, “removed\_email\_address@domain.invalid”, “removed\_email\_address@domain.invalid”]
