Как убрать из sitemap.xml все новости из подкатегорий и сами подкатегории?

foreach ( $cat_info as $cats ) {

if( $cats['parentid'] ) continue;

$row['date'] = strtotime($row['date']);

$cat_info = get_vars( "category" );
			
	if( ! is_array( $cat_info ) ) {
		$cat_info = array ();
				
		$db->query( "SELECT * FROM " . PREFIX . "_category ORDER BY posi ASC" );
				
		while ( $row = $db->get_row() ) {
					
			$cat_info[$row['id']] = array ();
					
			foreach ( $row as $key => $value ) {
				$cat_info[$row['id']][$key] = $value;
			}
				
		}
				
		set_vars( "category", $cat_info );
		$db->free();
	}
		
	$news_cats = explode(',', $row['category']);
	$stop = false;
	foreach( $news_cats as $cat_id ) {
		if( $cat_info[$cat_id]['parentid'] ){
			$stop = true;
		}
	}
	if( $stop ) continue;
