HTML DOM Parser Obtener tag "script"

luchos297 · #1 (**permalink**) 04/04/2016, 11:49

Buenas, estoy programando un crawler de un diario y recupero un tipo particular de noticias donde hay un carousel con muchas imagenes. Por lo que he visto, dentro del tag "img" del carousel asigna dinamicamente la url de la imagen que esta seleccionada en el carousel. Pero hay un tag "script" donde tiene codigo con los enlaces de todas las imagenes. Estoy intentando recuperarlo pero no puedo.

Hago lo siguiente:

Código PHP:

  $data31 = $this->html->getElementById('vplfgp_embeb');

$data32 = $data31->find('script', 0);

Pero cuando intento recuperar el texto javascript, me devuelve "", porque?

El texto a devolver seria el siguiente:

Código:

var vplfgo_popup_title='La Terraza citadina vibró con el talento de Felipe Staiti'; var vplfgo_popup  = null;vsm.loadScript('/portal/js/fgal.js?3.1.756.11',function (){waitobj('vplfgal',['popup',[{"i":"/files/image/669/669095/56e2bdd1cd588__500!.jpg?d=1457795569","w":"1366","h":"760","c":"Alexis Hernández, Natalia Fernández, Bruna Kappler y Ana
