Regex, extract e-mail from an HTML

Question

How can I extract e-mail, from this email:

Email <a href=""mailto:[email protected]"">[email protected]</a>

My Regex

(?<=Email)(.*)(?=<\/)

So far I was able to discard word Email and the 'a' closing tag (</a>) to this:

<a href=""mailto:[email protected]"">[email protected]

But how can I remove the 'a' opening tag along with href (<a href=""mailto:[email protected]"">) and only be left with the email?

Thanks

Ah, another one trying to collect email address from web pages? — arkascha, Sep 30 '16 at 13:28
`` ... why **`""`**... **`""`** ? Is that the problem that is preventing you from using an HTML parser? — Sinan Ünür, Sep 30 '16 at 13:29
Just using VBA to collect some data of a website, can't use .innertext on every page due to poor html structure, hence had to resort to regex. — Nikita Maximov, Sep 30 '16 at 13:33
very simple (e.g. for validation): `/\S+@\S+\.\S+/`. works for your example: `/([\w-\.]+@[\w-\.]+\.\w+)/` (http://regexr.com/3ebl6) — Simon Hänisch, Sep 30 '16 at 13:34
Thanks Simon, not quite what I was looking for, but it will do. Want to post your answer, so I can approve it? — Nikita Maximov, Sep 30 '16 at 13:37
`(?<=mailto:)[^"]+` perhaps. https://regex101.com/r/eAwWQp/1 — ʰᵈˑ, Sep 30 '16 at 13:39

Dont know if this helps but i wont do that with RegEx. would try to split after mailto: and search the next ". Everything between that COULD be an eMailadress.

The regular expression for this is: `(?<=mailto:)[^"]+` https://regex101.com/r/eAwWQp/1 – ʰᵈˑ Sep 30 '16 at 13:40

A real email regex is really complex, see this answer: https://stackoverflow.com/a/201378/2897426

A very simple email validation regex would be

/\S+@\S+\.\S+/

It doesn't work here because the email address is wrapped in text, so you can't use the \S for any non-whitespace character, but you can instead match \w (character, digit or underscore), - and . as "allowed" characters:

/([\w-\.]+@[\w-\.]+\.\w+)/

example: http://regexr.com/3ebl6

keep in mind that me@[127.0.0.1] would be a valid email address, too.
