        $rss = fetch_rss( $post['field7'] );
        $items = array_slice($rss->items, 0, 1);
        $blogLink = $items[0]['link'];
        $blogTitle = $items[0]['title'];
   }
} 


Since I am pulling whole thing, might not be applicable to your changes.
I tried checking for XML or RSS in the URL before it runs. So far, it appears to be working for me.
