     <answer score="20">answer 2</answer> 
     <answer score="30">answer 3</answer> 
     <answer score="40">answer 4</answer> 
    </question>

$evaluation_order = $questions['evaluation_order']; 
//echo $evaluation_order;

대답을 기다리는 것이 싫어. :-)

이것은 내 문제를 해결할 것입니다; 좋은 아이디어가 있다면 나와 공유하십시오.

$questions = simplexml_load_file("xml/workshop_evaluation_questions_1.xml"); 

$cnt1 = 0; 
foreach($questions->question as $k1=>$v1) { 
    echo ($questions->question[$cnt1]['text']); 
    echo ' => '; 
    echo count($questions->question[$cnt1]->answer); 
    echo '<br>'; 

    $cnt2 = 0; 
    foreach($questions->question[$cnt1]->answer as $k2=>$v2) { 
     echo $questions->question[$cnt1]->answer[$cnt2]; 
     echo ' => '; 
     echo $questions->question[$cnt1]->answer[$cnt2]['score']; 
     echo '<br>'; 
     $cnt2++; 
    } 
    $cnt1++; 
    echo '<hr>'; 
}
