Migration

Change the use statement from TYPO3\CMS\Core\Html\HtmlParser to TYPO3\CMS\Core\Service\MarkerBasedTemplateService and create an instance of this service class. The methods are not static anymore, but named as before.

$templateService = GeneralUtility::makeInstance(MarkerBasedTemplateService::class);
$templateService->getSubpart()
$templateService->substituteSubpart()
$templateService->substituteSubpartArray()
$templateService->substituteMarker()
$templateService->substituteMarkerArray()
$templateService->substituteMarkerAndSubpartArrayRecursive()
