Replace in text but skip replacement in tags?

Question

PHP

There is a code like this replaces once in the text:

function str_replace_once($search, $replace, $text) 
{ 
$pos = strpos($text, $search); 
return $pos!==false ? substr_replace($text, $replace, $pos, strlen($search)) : $text; 
}

$str = 'Helo World!'; 
$str = str_replace_once('l', 'll', $str); 
// результат 'Hello World!';

tell me how to add exceptions to the conditions so that replacements do not occur if the text is in tags
, that is, if

$str = '<a href="(тут любая ссылка)">Helo World!</a>';

then the substitution will not take place.
