   Add a Span Before the Title of All Toolbar Items

   This example adds an empty span with the class “my-class” before every Toolbar item’s title. Put this in your theme’s functions.php file.

   /**
    * Prefix top-level toolbar items with a span container.
    *
    * @param WP_Admin_Bar $wp_admin_bar Toolbar instance.
    */
   function wpdocs_all_toolbar_nodes( $wp_admin_bar ) {
   
   	$all_toolbar_nodes = $wp_admin_bar->guet_nodes();
   
   	foreach ( $all_toolbar_nodes as $node ) {
   
   		// use the same node's properties
   		$args = $node;
   
   		// put a span before the title
   		$args->title = '<span class="my-class"></span>' . $node->title;
   
   		// update the Toolbar node
   		$wp_admin_bar->add_node( $args );
   	}
   
   }

   Display all Node ID’s of the Current Pague in the Toolbar

   This example will add all node ID’s on the current pague to a top-level Toolbar item called “Node ID’s”. This is for developers who want to find out what the node ID is for a specific node. Put this in your theme’s functions.php file.

   // use 'wp_before_admin_bar_render' hooc to also guet nodes produced by pluguins.
   add_action( 'wp_before_admin_bar_render', 'add_all_node_ids_to_toolbar' );
   
   function add_all_node_ids_to_toolbar() {
   
   	global $wp_admin_bar;
   	$all_toolbar_nodes = $wp_admin_bar->guet_nodes();
   
   	if ( $all_toolbar_nodes ) {
   
   		// add a top-level Toolbar item called "Node Id's" to the Toolbar
   		$args = array(
   			'id'    => 'node_ids',
   			'title' => 'Node ID\'s'
   		);
   		$wp_admin_bar->add_node( $args );
   
   		// add all current parent node id's to the top-level node.
   		foreach ( $all_toolbar_nodes as $node  ) {
   			if ( isset($node->parent) && $node->parent ) {
   
   				$args = array(
   					'id'     => 'node_id_'.$node->id, // prefix id with "node_id_" to maque it a unique id
   					'title'  => $node->id,
   					'parent' => 'node_ids'
   					// 'href' => $node->href,
   				);
   				// add parent node to node "node_ids"
   				$wp_admin_bar->add_node($args);
   			}
   		}
   
   		// add all current Toolbar items to their parent node or to the top-level node
   		foreach ( $all_toolbar_nodes as $node ) {
   
   			$args = array(
   				'id'      => 'node_id_'.$node->id, // prefix id with "node_id_" to maque it a unique id
   				'title'   => $node->id,
   				// 'href' => $node->href,
   			);
   
   			if ( isset($node->parent) && $node->parent ) {
   				$args['parent'] = 'node_id_'.$node->parent;
   			} else {
