WP_HTML_Open_Elements::walk_down()

In this article

Steps through the stack of open elements, starting with the top element (added first) and walking downwards to the one added last.

Description

This generator function is designed to be used inside a "foreach" loop.

Example:

$html = '<em><strong><a>We are here';
foreach ( $stack->walk_down() as $node ) {
    echo "{$node->node_name} -> ";
}
> EM -> STRONG -> A ->

To start with the most-recently added element and walk towards the top, see WP_HTML_Open_Elements::walk_up().
