You solution is not enough as I read here: http://www.sk-typo3.de/Cache-
loeschen-aus-der-Extension.213.0.html

This code I use now is a little better way:

		$dbResult = $GLOBALS['TYPO3_DB']->exec_SELECTquery(
		'pid', 'tt_content', 'list_type="visualizexml_pi1"'
		);
		
		if (!$dbResult) {
			return;
		}

		$pageIds = array();
		while ($row = $GLOBALS['TYPO3_DB']->sql_fetch_assoc($dbResult)) {
			$pageIds[] = $row['pid'];
		}
		$tce = t3lib_div::makeInstance('t3lib_TCEmain'); 
		 foreach (array_unique($pageIds) as $pid) {
				$tce->clear_cacheCmd($pid);
		 } 

Thanks
