buenas:

estoy tratando de leer este rss: http://www.softonic.com/rss/2/feed_l...actualized.xml de esta manera:

Código PHP:

  $xml=simplexml_load_file('http://www.softonic.com/rss/2/feed_last_news_by_date_actualized.xml');

    var_dump($xml);

y me devuelve esto:

object(SimpleXMLElement)#1 (2) { ["@attributes"]=> array(1) { ["version"]=> string(3) "2.0" } ["channel"]=> object(SimpleXMLElement)#2 (8) { ["title"]=> string(37) "Windows novedades (Windows): Softonic" ["description"]=> string(297) "El website hispano lÃ*der en descargas de shareware, freeware, juegos, salvapantallas y software gratis.

["comments"]=> object(SimpleXMLElement)#83 (0) { } ["guid"]=> string(5) "31360" ["pubDate"]=> string(6) " +0100" } } } }

yo quiero obtener:

["pubDate"]=> string(31) "dom, 30 mar 2008 21:15:33 +0100"

y :
["item"]=> array(20) { [0]=> object(SimpleXMLElement)#4 (6) { ["title"]=> object(SimpleXMLElement)#24 (0) { } ["link"]=> string(45) "http://firefox-portable-2-es-es.softonic.com/" ["description"]=> object(SimpleXMLElement)#25 (0) { } ["comments"]=> object(SimpleXMLElement)#26 (0) { } ["guid"]=> string(5) "57303" ["pubDate"]=> string(6) " +0100" } [1]=> object(SimpleXMLElement)#5 (6) { ["title"]=> object(SimpleXMLElement)#27 (0) { } ["link"]=> string(27) "http://xnview.softonic.com/" ["description"]=> object(SimpleXMLElement)#28 (0) { } ["comments"]=> object(SimpleXMLElement)#29 (0) { } ["guid"]=> string(5) "14433" ["pubDate"]=> string(6) " +0100" } [2]=> object(SimpleXMLElement)#6 (6) { ["title"]=> object(SimpleXMLElement)#30 (0) { } ["link"]=> string(26) "http://joost.softonic.com/" ["description"]=> object(SimpleXMLElement)#31 (0) { } ["comments"]=> object(SimpleXMLElement)#32 (0) { } ["guid"]=> string(5) "62130" ["pubDate"]=> string(6) " +0100" } ......

intente con

Código PHP:

  $result = $xml->xpath('//channel');

pero no puede acceder a los elementos de ese array que me genera, alguien me puede guiar un poco mas....

desde ya muchas gracias

bueno sin quererlo encontre la solución se la dejo para el que quiera usarla:

Código PHP:

  $Noticias = simplexml_load_file('http://www.softonic.com/rss/2/feed_last_news_by_date_actualized.xml');

    if (!count((array)$Noticias->item))

    //Si es 0 quiere decir que existe la etiqueta channel

    {

        echo "Publicado el: ".$Noticias->channel->pubDate."<br>";

        foreach($Noticias->channel->item as $Noticia)

        {

            echo "titulo: ".utf8_decode($Noticia->title)."<br>";

            echo "description: ".utf8_decode($Noticia->description)."<br>";

        }

    }

    else

    {

        foreach($Noticias->item as $Noticia)

        {

            echo "titulo: ".utf8_decode($Noticia->title)."<br>";

            echo "description: ".utf8_decode($Noticia->description)."<br>";

 
        }

    }
