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...
