wp_nav_menu过滤，删除特定链接

Question

I'm trying to remove a specific link from my wordpress menu:

<li class="ubermenu-item ubermenu-item-type-post_type ubermenu-item-object-page ubermenu-item-1 ubermenu-item-level-0 ubermenu-column ubermenu-column-auto" ><a class="ubermenu-target ubermenu-item-layout-default ubermenu-item-layout-text_only" href="/first/" tabindex="0"><span class="ubermenu-target-title ubermenu-target-text">First</span></a></li>

<li class="ubermenu-item ubermenu-item-type-post_type ubermenu-item-object-page ubermenu-item-2 ubermenu-item-level-0 ubermenu-column ubermenu-column-auto" ><a class="ubermenu-target ubermenu-item-layout-default ubermenu-item-layout-text_only" href="/second/" tabindex="0"><span class="ubermenu-target-title ubermenu-target-text">Second</span></a></li>

<li class="ubermenu-item ubermenu-item-type-post_type ubermenu-item-object-page ubermenu-item-3 ubermenu-item-level-0 ubermenu-column ubermenu-column-auto" ><a class="ubermenu-target ubermenu-item-layout-default ubermenu-item-layout-text_only" href="/third/" tabindex="0"><span class="ubermenu-target-title ubermenu-target-text">Third</span></a></li>


function remove_link( $menu ) {
    return str_replace( '<a href="', '<a>', $menu );
}
add_filter( 'wp_nav_menu', 'remove_link' );

The link that I'm trying to remove has the .ubermenu-item-3 attached to the li element. How may I do this?

Both versions below. read the comments! This depends on domdocument, most php installations will have it, but some custom set ups don't.

function remove_link( $html ) {
    $dom->loadHTML($html);
    $links= $dom->getElementsByTagName('li');

    foreach($links as $data){

        if(strpos($data->getAttribute('class'), 'ubermenu-item-3') !== false){

            //remove the entire li - comment out if just removing the href
            $data->parentNode->removeChild($data);

            //alternatively change the href as per your code (comment out if using remove the entire li) 
            //foreach($data->getElementsByTagName('a') as $as){
            //  $as->setAttribute('href', '');
            //}     
        }

    }

    $html= $dom->saveHTML();

    return $html;

}

add_filter( 'wp_nav_menu', 'remove_link' );
