Returning HTML from a Drupal 8 form programmatically:

invoke a form within a block or custom module page

$form = \Drupal::formBuilder()->getForm('Drupal\example\Form\ExampleForm');

if (file_exists(drupal_get_path('module', 'complimentmigration') . '/MyManual08-088-18.xml')) {
      $xml = simplexml_load_file(drupal_get_path('module', 'complimentmigration') . '/MyManual08-088-18.xml');
      $xml2 = (string) $xml->section->version->title;
      drupal_set_message('
' . print_r($xml2, TRUE) . '
');

    }

so the ball will move accordingly every dt
