Answer 1

Just try with:

$input = '<b>Text 1</b><br><i>Text 2</i>
          Some text - very long and not interesting.
          <b>Text 3</b><br><i>Text 4</i>';
$dom = new DOMDocument();
$dom->loadHTML($input);
$xpath = new DOMXpath($dom);
$items = $xpath->query('//i | //b');

$output = [];
foreach ($items as $item) {
    $output[] = $item->textContent;
}

var_dump($output);

Output:

array (size=4)
  0 => string 'Text 1' (length=6)
  1 => string 'Text 2' (length=6)
  2 => string 'Text 3' (length=6)
  3 => string 'Text 4' (length=6)
