Array problem

Array problemer
Jeg skal have nogle xml data over i et array.

min kode til dette ser sådan ud:

--------------------
function XmlToArray()
    {
    $file_url = $this->XmlConnectionUrl(0);
    $xmlFileData = file_get_contents($file_url);
    $xmlData = new SimpleXMLElement($xmlFileData);
       
       
    foreach($xmlData->questions->question as $question)
    {
            foreach($question->answers->answer as $answer)
        {
            if($answer->attributes()->uid == 1153)
            {
                $arrayAnswer[] = $answer;
            }
        }
           
$countries[] = array($question->question_title,$question->question_text,$arrayAnswer);   
           
    }
       
        return $countries;
       
    }

Mit problem er at $arrayAnswer kommer til at indeholde svarene fra både spørgsmål 1 og spørgsmål 2.

Jeg vil gerne lave det sådan at $countries[0][2] kun indeholder svarmulighederne knyttet til spørgsmål 1 og $countries[1][2] fra spørgsmål 2 osv.

Hvordan løser jeg dette?
