Answer 1

Through PCRE verb (*SKIP)(*F).

<[^<>]*>(*SKIP)(*F)|[A-Z0-9._%+-]+@([A-Z0-9.-]+.[A-Z]{2,4}|[A-Z0-9.-]+)

DEMO

<[^<>]*> matches all the tags and the following PCRE verb (*SKIP)(*F) makes the match to fail completely. Then the regex engine tries to match the pattern which was at the right of | symbol against the remaining string.

$re = "/<[^<>]*>(*SKIP)(*F)|[A-Z0-9._%+-]+@([A-Z0-9.-]+\.[A-Z]{2,4}|[A-Z0-9.-]+)/mi";
$str = "<div data="[email protected],[email protected]"><a href="[email protected]" > [email protected], <b>[email protected]</b> other text, [email protected], ,<i>[email protected]</i></a></div >
";
$subst = "[---]";
$result = preg_replace($re, $subst, $str);
echo $result;

Output:

<div data="[email protected],[email protected]"><a href="[email protected]" > [---], <b>[---]</b> other text, [---], ,<i>[---]</i></a></div >
