    In xml is ‘zone’, but in php you have ‘zona’.
    You not need to add the id and name attributes in array keys, just put the tag name.

    $info = "information: ".$array['trend']['zone']['subzone']['text'];

    You don’t have to convert your SimpleXML object to an array to access values from it, you can just access them like object variables:

    $xml = simplexml_load_string($xmlstring, "SimpleXMLElement", LIBXML_NOCDATA);
echo $xml->trend->zone->subzone->text;

    Output:

    I want this text.

    You can use XPath to query the exact node you want :

    $xml = simplexml_load_string($xmlstring);
$nodes = $xml->xpath("/root/trend/zone[@id = 809 and @name= 'AGi']/subzone[@id = 809 and @name = 'AGi']/text") ;
$text = (string)$nodes[0] ;
echo $text ; // I want this text.
