This is a modification of a similar script I wrote a couple of days ago for someone who wanted to load a list of animals.

Put the following into a file called questions.xml, and put the file
the same place the .swf is.

Code:
<questionList>
       <question q="What is furry and purrs?" a="A cat" />
       <question q="What is furry and barks?" a="A dog" />
       <question q="What is not furry"        a="A shaved cat" />
</questionList>
Then put this actionscript on frame 1 of your movie. It loads the questions into an array of question/answer pairs.

Code:
// XML Question Loader - Jim Bumgardner

qList = new Array();

// This is a recursive function that
// walks thru all the nodes in your XML
// and loads up the ones you're 
// interested in into the qList array.

loadNode = function(it)
{
  if (it.nodeName == 'question') {
    var qPair = new Array();
    qPair.q = it.attributes['q'];
    qPair.a = it.attributes['a'];
    qList.push(qPair);
  }
  else if (it.nodeName == "questionList") 
  {
    // process any questionList properties here 
    // - there aren't any at the moment.  
    // Note that the 'questionList' tag is 
    // completely ignored - this will still
    // work without that tag.
  }
  if (it.hasChildNodes()) {
    for (var i = 0; i < it.childNodes.length; ++i)
        loadNode(it.childNodes[i]);
  }
}

// when this function is called, we're done loading  
// - do something with your data.
// Most likely you want to jump to a frame in your movie where you play the game, but I'll just output a few values

function finishInit()
{
  trace(qList.length + " questions loaded:");
  // Pick a random question
  var r = random(qList.length);
  trace("a random question: " + qList[r].q);
  trace("...and its answer: " + qList[r].a);
}

var myxml = new XML();

myxml.onLoad = function()
{
  // initialize array again, in case 
  // we're calling this twice...
  qList = new Array(); 

  loadNode(this);
  finishInit();
}

myxml.load("questions.xml");

// A common mistake is to attempt to access the data here.  Don't -- it is not loaded at this point 
// myxml.load() is an asynchronous function - it returns before it is finished.
// The finishInit() function (above) will be called when the data is ready to go...
