<p>RegExp to validate email addresses</p> <p><b>New page</b></p><div>I see that in this page it is advised to use the following RegExp to validate email addresses:<br /> Code:<br /> <br /> /^.+?@.+?\..+$/<br /> <br /> However, this would validate an email address containing whitespace, and also lists of email addresses separated by puctuation.<br /> I&#039;ve found this RegExp would validate correctly an email address: <br /> ^([^\x00-\x20\x22\x28\x29\x2c\x2e\x3a-\x3c\x3e\x40\x5b-\x5d\x7f-\xff]+|\x22([^\x0d\x22\x5c\x80-\xff]|\x5c[\x00-\x7f])*\x22)(\x2e([^\x00-\x20\x22\x28\x29\x2c\x2e\x3a-\x3c\x3e\x40\x5b-\x5d\x7f-\xff]+|\x22([^\x0d\x22\x5c\x80-\xff]|\x5c[\x00-\x7f])*\x22))*\x40([^\x00-\x20\x22\x28\x29\x2c\x2e\x3a-\x3c\x3e\x40\x5b-\x5d\x7f-\xff]+|\x5b([^\x0d\x5b-\x5d\x80-\xff]|\x5c[\x00-\x7f])*\x5d)(\x2e([^\x00-\x20\x22\x28\x29\x2c\x2e\x3a-\x3c\x3e\x40\x5b-\x5d\x7f-\xff]+|\x5b([^\x0d\x5b-\x5d\x80-\xff]|\x5c[\x00-\x7f])*\x5d))*$<br /> <br /> As far as I know, there is not a neater option.<br /> How about changing the page content?</div>
