Ciao a tutti, sto usando simplexml per leggere un feed rss di un blog creato in wordpress, lo script è questo
Codice PHP:
$dato="http://www.xxxx.it/blog/feed/";

    $xml = simplexml_load_file($dato);
      foreach($xml->channel as $channel)  
      {
          foreach($channel as $item){

  echo '<div id="pette" style="float:left; width:830px; height:auto; margin-bottom:10px;">[b]'.$item->title.'[/b]'.$item->description.'</div>';

            
          }

      } 
Ci sono dei momenti in cui non riesce a leggere il feed, vorrei mettere una condizione in modo che lo script se non riesce a caricare il feed mi lanci un messaggio del tipo : dati in aggiornamento.
Come posso fare ?

Questo è xml
codice:
<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0"
	xmlns:content="http://purl.org/rss/1.0/modules/content/"
	xmlns:wfw="http://wellformedweb.org/CommentAPI/"
	xmlns:dc="http://purl.org/dc/elements/1.1/"
	xmlns:atom="http://www.w3.org/2005/Atom"
	xmlns:sy="http://purl.org/rss/1.0/modules/syndication/"
	xmlns:slash="http://purl.org/rss/1.0/modules/slash/"
