HTML entities not importing in XML file

Hey ananda, well, I don't think it should be converted, this module covers specific field configurations in the importer.
It sounds more like a misconfiguration, or missed plugin, I think you should have in the export correctly decoded values.
Example of working XML source:

<description>
<![CDATA[ <p>

However, if you need to support your case, I think we can manage the custom feeds plugin (your project plugin), you can try more plugins from https://www.drupal.org/project/feeds_ex → or modify data using feeds events:

 your_module.importer.event_subscriber:
    class: Drupal\your_module\EventSubscriber\ImporterEventSubscriber
    tags:
      - { name: event_subscriber }

  /**
   * Event triggered during the parsing of the feed.
   *
   * This is called after actual parsing is done. See the priority in
   * getSubscribedEvents().
   *
   * @param \Drupal\feeds\Event\ParseEvent $event
   *   The parse feed event.
   */
  public function onParse(ParseEvent $event): void {
foreach ($event->getParserResult() as $item) {
      /** @var \Drupal\feeds\Feeds\Item\DynamicItem $item */
      $guids[] = $item->get('xpath_feeds_item_guid');

      // Decode all HTML entities in all the text to avoid problems with data
      // that is ran through check_plain() when being displayed.
      $item_array = $item->toArray();
      foreach ($item_array as &$result) {
        if (is_array($result)) {
          foreach ($result as &$value) {
            $value = html_entity_decode($value, ENT_QUOTES, 'UTF-8');
            // Remove Unicode control characters and the Unicode Private Use
            // Area which is undefined.
            $value = preg_replace('/[\x{007F}-\x{009F}\x{E000}-\x{F8FF}]/u', '', $value);
          }
        }
        elseif (is_string($result)) {
          $result = html_entity_decode($result, ENT_QUOTES, 'UTF-8');
          // Remove Unicode control characters and the Unicode Private Use Area
          // which is undefined.
          $result = preg_replace('/[\x{007F}-\x{009F}\x{E000}-\x{F8FF}]/u', '', $result);
        }
      }
      $item->fromArray($item_array);
    }

Also, this module https://www.drupal.org/project/feeds_tamper → provides a way to modify data and you can try to decode it first.

Could you ping me in Slack in Drupal?

hi,

Thanks, however I can't join the Drupal slack: You can use any account with the domain:
association.drupal.org
socialenterprises.net

I already tried before the tamper module, and it did not work.

The bizarre thing is: half of the xml's work to import with converted html entities, and the other half gives this weird issue.

Can I give you access so you can check it on this sandbox-dev site ?

Hi, you must use any method from my comment #2.
It is not this module issue.
