     * Breadcrumb Trail - A breadcrumb menu script for WordPress.

     * Breadcrumb Trail is a script for showing a breadcrumb trail for any type of page.  It tries to
     * anticipate any type of structure and display the best possible trail that matches your site's
     * permalink structure.  While not perfect, it attempts to fill in the gaps left by many other
     * breadcrumb scripts.

  • У меня почти получилось, вот осталось немного

    $item = ! empty( $matches ) ? sprintf( ‘%s<span itemprop=»name»>%s</span>%s’, $matches[1], $matches[2], $matches[3] ) : sprintf( ‘<span itemprop=»name»>%s</span>’, $item );

    // Wrap the item with its itemprop.
    $item = ! empty( $matches )
    ? preg_replace( ‘/(<a.*?)([\'»])>/i’, ‘$1$2 itemprop=$2item$2>’, $item )
    : sprintf( ‘<span itemprop=»item»>%s</span>’, $item );

    if ( $item_count === $item_position ) {
    $item_class = »;
    $meta = sprintf( », absint( $item_position ) );
    $attributes = » . $item_class . »;
    }

    Нужен span чтобы был без itemprop, для последней позиции — if (item = item_position) как раз ее указывает
