Llevo peleándome y buscando varias horas y no encuentro la solución.
Intento extraer datos de un feed de una búsqueda de youtube a variables php.
Os pongo el feed y luego lo que estoy intentando.
Los datos que intento extraer los pongo en rojo
El feed.
Código:
Bueno el "thumbnail" si que me sale.<?xml version='1.0' encoding='UTF-8'?>

Ahí va mi php:
Código PHP:
$feedURL = "http://gdata.youtube.com/feeds/api/channels?q=$q&v=2";
$sxml = simplexml_load_file($feedURL);
foreach ($sxml->entry as $entry) {
//aqui saco la url de la imagen sin problema
$media = $entry->children('http://search.yahoo.com/mrss/');
$attributes = $media->thumbnail->attributes();
$thumbnail = (string)$attributes['url'];
//ahora intento las otras dos que me dan resultado en blanco
$autor = $entry->autor->name;
$titulo = $entry->title;
Muchas gracias.
