Examples

// Add a specific class to the anchor link when the type is 'page'
add_filter( 'uo_build_anchor_links', function( $link, $permalink, $title, $type ) {
    if ( 'page' === $type ) {
        // Assuming $link is a string containing the HTML.
        // We'll add a class to the <a> tag.
        $link = str_replace( 'class="trail-begin"', 'class="trail-begin page-link"', $link );
    }
    return $link;
}, 10, 4 );

// Remove the 'rel="nofollow"' attribute if the permalink is internal
add_filter( 'uo_build_anchor_links', function( $link, $permalink, $title, $type ) {
    // A simplified check for internal permalink. In a real scenario,
    // you might use parse_url and compare with site_url().
    if ( strpos( $permalink, site_url() ) !== false ) {
        $link = str_replace( 'rel="nofollow"', '', $link );
    }
    return $link;
