Question

I’ve got a string that contains:

@from = "John Doe <[e-mail]>"

When I do:

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

I get no results. I’m trying to extract the email address on it’s own.

I tried removing the \b’s but this did not work either.

Any help would be much appreciated.

Answer 1

Your expression works fine: rubular

The problem is the quotes around your regular expression means that it is interpreted as a plain text string rather than a regular expression. Removing the quotes solves the problem: ideone

@from = "John Doe <[e-mail]>"
@from.scan(/\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i) { |x| puts x } 

Output:

[e-mail]
