AS3 XML 到多维数组

Question

我到处都看过，虽然有很多解释，但我似乎无法理解它。

这是我的 xml 结构：

 <question> 
            <q1> Who coined the term “Clinical Psychology”? </q1>       
            <answer> Lightner Witmer </answer>

            <option1> Stanley Hall </option1>
            <option2> Lightner Witmer </option2>
            <option3> Henry P. David </option3>
    </question>

我可以循环遍历并挑选出问题和答案，然后将它们放入单独的数组中。我遇到的问题是循环并将选项拉入多维数组中，如下所示：

var one:Array = new Array( 3 ); 
one[0] = ["Stanley Hall", "Lightner Witmer", "Henry P. David"];
one[1] = ["Stanley Hall", "Lightner Witmer", "Henry P. David"];
one[2] = ["Stanley Hall", "Lightner Witmer", "Henry P. David"];

任何帮助将不胜感激。

Answer 1

    var answers:Array = [];

    for(var i = 0; i< xml.question.length; i++){
    var node:Array = [];
    node.push(xml.question[i].option1);
    node.push(xml.question[i].option2);
    node.push(xml.question[i].option3);

//or
    var node:Array = [xml.question[i].option1,xml.question[i].option2,xml.question[i].option3];

    answers.push(node);

    }

现在可以检索问题的答案：

answers[questionIndex][answerIndex];

希望有帮助

我不确定您是否以您想要的形式设置数组，但是，请关闭您发布的代码。
你尝试过吗？

var one:Array = new Array( 3 ); 
one[0] = new Array( "Stanley Hall", "Lightner Witmer", "Henry P. David" );
one[1] = new Array( "Stanley Hall", "Lightner Witmer", "Henry P. David" );
one[2] = new Array( "Stanley Hall", "Lightner Witmer", "Henry P. David" );

对于这样的东西，我更喜欢有一个以对象作为元素的问题数组。每个对象都会保存有关该问题的所有信息。这将允许为每个问题分配一个自定义类别。或者可以使用基本的动态对象

var questions:Array = new Array();

var obj:Object = new Object();
obj.question = "Who coined the term 'Clinical Psychology'?"
obj.correctAnswer = "Lightner Witmer";
obj.possibleAnswers =new Array( "Stanley Hall", "Lightner Witmer", "Henry P. David" );

questions.push( obj );
