I think you meant extract emails from document, right? I'd probably find `@` and iterate before and after unless I get posix punct, space, characters. But it'll probably give some false matches. So its really hard to find 100% emails from an arbitrary text. This is because valid email can contain many different type of characters. According to RFC 822 space is a valid character in email. So finding all the valid emails is tough. In a *trivial situation* an email would be separated by space. So find @ first. Then go back and front to find the first space. You'll get most common emails. Something like using this regex pattern [^[:space:]<@]+@[^[:space:]>]+ would suffice. But keep in mind, it'll work on trivial cases. Not on special cases. Regular expression can not be used on special cases. Here is full RFC-822 compliant email matching regular expression http://ex-parrot.com/~pdw/Mail-RFC822-Address.html
