This will work in most cases:

$result = preg_replace('/^((?:[^<"]|(?:<[^>]*>))*)"([^"]*)"/', "$1'$2'", $str);

It will not work if you have a > character in an HTML attribute. To catch all those edge cases you should avoid regex, and look into more powerful tools designed for parsing HTML, since HTML is not a regular language.
