Regular expression for validating multiple email

In various use-cases, but especially at web-based registration forms we need to make sure the value we received is a valid e-mail address.Another common use-case is when we get a large text-file (a dump, or a log file) and we need to extract the list of e-mail address from that file.Many people know that Perl is powerful in text processing and that using regular expressions can be used to solve difficult text-processing problems with just a few tens of characters in a well-crafted regex.

One of the best (and maybe only valid) use-cases is when you would like to teach regexes.RFC822 specifies how an e-mail address must look like but we know that e-mail addresses look like this: where the "username" part can contain letters, numbers, dots; the "domain" part can contain letters, numbers, dashes, dots.For example: examples/email_It properly verifies if an e-mail is valid, it even removes unnecessary white-spaces from both ends of the e-mail address, but it cannot really verify if the given e-mail address is really the address of someone, and if that someone is the same person who typed it in, in a registration form.These can be verified only by actually sending an e-mail to that address with a code and asking the user there to verify that indeed s/he wanted to subscribe, or do whatever action triggered the email validation.Hi All, I want to validate multiple email addresses in GWT. Email but it validates a single email address only and does not accept comma or any other seperator.
