Regex: find email address when not wrapped in HTML tag

Question

Given a text with email addresses I would like to match all the ones that are not wrapped inside an "a" tag. And I can only do it with a regex.

THIS MATCH:

something@something.else

THIS DOES NOT MATCH:

<a href="mailto:someone@example.com?Subject=Hello%20again" target="_top">Send Mail</a>

Anyone? Thanks.

Which language or tool are you using? What is the e-mail format? What have you already tried? — logi-kal, Jul 21 '16 at 11:01
[This is worth a read](http://www.regular-expressions.info/email.html) if you're going to match email addresses with a regex. — James Thorpe, Jul 21 '16 at 11:04
At the moment I use http://regexr.com/ for testing. I managed to find all the content wrapped in "a" tags by: ]*>(.*?)<\/a> but I haven't find any way to perform the lookahead for @ symbols (format of the email is not important for my case, finding the @ symbol is sufficient). I have this not-working version: (?!]*>(.*?)<\/a>).*@.* — Andrea, Jul 21 '16 at 11:08

Here's the basics: /<a(?:\s[^>]*)?>[\W\w]*?<\/a>|([a-z]+@[a-z]+\.[a-z]+)/i

You'll get every link and every text email, but only the text email will be grouped. Not sure if that's what you wanted, but I think that's the only way you'll be able to do it with a single regex.

Of course, you'd finesse the email recognition and link recognition, but that all depends on how far you want to go. – Whothehellisthat Jul 21 '16 at 13:50
