Leyendo rss

[geminis19]

Hola, estoy intentando leer un Rss, el código es el siguiente:

Código PHP:

  class Rss{
 
    public $file;
    public $feed;
    public $currently_writing;
    public $main;
    public $item_counter;
    
    public function __construct()
    {
        $this->feed=array();
        $this->this->currently_writing="";
        $this->main="";
        $this->item_counter=0;
    }
        
    public function startElement($parser, $name, $attrs) 
    {
           switch($name) {
               case "RSS":
               case "RDF:RDF":
               case "ITEMS":
                   $this->currently_writing = "";
                   break;
               case "CHANNEL":
                   $this->main = "CHANNEL";
                   break;
               case "IMAGE":
                   $this->main = "IMAGE";
                   $this->feed['rss']["IMAGE"] = array();
                   break;
               case "ITEM":
                   $this->main = "ITEMS";
                   break;
               default:
                   $this->currently_writing = $name;
                   break;
           }
    }
 
    public function endElement($parser, $name) 
    {
       $this->currently_writing = "";
       if ($name == "ITEM") {
           $this->item_counter++;
       }
    }
 
    public function characterData($parser, $data) 
    {
        if ($this->currently_writing != "") {
            switch($this->main) {
                case "CHANNEL":
                    if (isset($this->feed['rss'][$this->currently_writing])) {
                        $this->feed['rss'][$this->currently_writing] .= $data;
                    } else {
                        $this->feed['rss'][$this->currently_writing] = $data;
                    }
                    break;
                case "IMAGE":
                    if (isset($this->feed['rss'][$this->main][$this->currently_writing])) {
                        $this->feed['rss'][$this->main][$this->currently_writing] .= $data;
                    } else {
                        $this->feed['rss'][$this->main][$this->currently_writing] = $data;
                    }
                    break;
                case "ITEMS":
                    if (isset($this->feed['rss'][$this->main][$this->item_counter][$this->currently_writing])) {
                        $this->feed['rss'][$this->main][$this->item_counter][$this->currently_writing] .= $data;
                    } else {
                        $this->feed['rss'][$this->main][$this->item_counter][$this->currently_writing] = $data;
                    }
                    break;
            }
        }
    }
 
    function getRss($file)
    {
        $this->file=$file;
        if(file_get_contents($this->file))
        {
            $xml_parser=xml_parser_create();
            xml_set_element_handler($xml_parser, $this->startElement, $this->endElement);
            xml_set_character_data_handler($xml_parser, $this->characterData);
            
            if(!($fp = fopen($this->file, "r")))
                die("could not open XML input");
            
            while($data=fread($fp, 4096))
            {
                if (!xml_parse($xml_parser, $data, feof($fp)))
                    die(sprintf("XML error: %s at line %d", xml_error_string(xml_get_error_code($xml_parser)), xml_get_current_line_number($xml_parser)));
            }
            
            xml_parser_free($xml_parser);            
            return $this->feed;
        }
        else
            return array("error"=>"Error a leer el XML.");
    }
}
 
$rss=new Rss();
var_dump($rss->getRss("http://www.cronicachillan.cl/cronica_chillan_base/site/edic/base/rss/portada.xml")); 
   

Esto me retorna:
array(0) { }

Es raro, el feed esta bueno, también e probado con otros y no funciona...

saludos...
