WP_HTML_Open_Elements::walk_up()

In this article

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

Description

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

Example:

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

To start with the first added element and walk towards the bottom, see WP_HTML_Open_Elements::walk_down().
