regular expression for email address formats
I have the following regulare expression which I am using to validate email address format.
This allows addresses of the form
address@oracle.co.uk
^[-a-zA-Z0-9._]+\@[-a-zA-Z0-9]+\.[-a-zA-Z0-9]+\.[-a-zA-Z0-9]+$
And of course this allows addresses of the form
address@oracle.com
^[-a-zA-Z0-9._]+\@[-a-zA-Z0-9]+\.[-a-zA-Z0-9]+$
What I'm looking for is something which will allow both.
