Multidimensional array, loop of buttons, and loading swf/img/txt from xml

Okay, here goes: What I'm trying to do is create a multidimensional array which will pull text, swfs, and/or images from an xml file based on which button is clicked.

What I don't understand is how to pull the swf or image file from the file like I have with the text. Truth be told, I'm completely lost and could really use some help fixing this. I need to pull text and images or the swf file from the xml depending on which button is clicked and I tried to put this together, but I've given myself a headache trying to understand where I went wrong.

var pageXML:XML;

//Load the XML file.
var pageXMLLoader = new URLLoader();
pageXMLLoader.load(new URLRequest("scripts/xml/content.xml"));
pageXMLLoader.addEventListener(IOErrorEvent.IO_ERROR, xmlIOErrorHandler); 
pageXMLLoader.addEventListener(Event.COMPLETE, pageXMLLoaded);

// Intro page variables for title
var swfContainer:Sprite = new Sprite();
var imgContainer:Sprite = new Sprite();
var imgLoader:Loader = new Loader();
var swfLoader:Loader = new Loader();

//This function is called when the XML file is loaded
function pageXMLLoaded(e:Event):void {

    //Create a new XML object from the loade开发者_JS百科d XML data
    pageXML = new XML(e.target.data);
    imgLoader.load(new URLRequest(pageXML.pages.page.image));
    swfLoader.load(new URLRequest(pageXML.pages.page.swfURL));
    trace(pageXML.pages.page.image);
    trace(pageXML.pages.page.swfURL);

}

// Choose page transition function
function choosePageTransition(e:MouseEvent):void {
    var pageNumber:uint;

    mcContent.y = 30; // Why do I need to reset the y position each time?

// Set up if for mouse click
if (e.type == MouseEvent.CLICK) {

    // Switch based on target name
    switch (e.currentTarget.name) {
        case "navBtn0" :
            trace(e.currentTarget.name);
            pageNumber = 1;

            mcContent.removeChildAt(0);

            mcContent.addChildAt(pageContent,0);

            pageContent.addChild(contentRBottomTxt);
            pageContent.addChild(contentRTopTxt);
            pageContent.addChild(contentTxt);
            pageContent.addChild(headingTxt);

            break;

        case "navBtn1" :
            trace(e.currentTarget.name);
            pageNumber = 2;

            mcContent.removeChildAt(0);

            mcContent.addChildAt(pageContent,0);

            pageContent.addChild(contentRBottomTxt);
            pageContent.addChild(contentRTopTxt);
            pageContent.addChild(contentTxt);
            pageContent.addChild(headingTxt);

            break;

        case "navBtn2" :
            trace(e.currentTarget.name);
            pageNumber = 3;

            mcContent.removeChildAt(0);

            mcContent.addChildAt(pageContent,0);

            pageContent.addChild(contentRBottomTxt);
            pageContent.addChild(contentRTopTxt);
            pageContent.addChild(contentTxt);
            pageContent.addChild(headingTxt);

            break;

        ... code shortened 
    }


    // Loop through the XML file
    for each (var page:XML in pageXML.pages.page) {

        // "page.@pagenumber" points to "pagenumber" in the XML file.
        if (page.@ pagenumber == pageNumber) {

            // Set the title
            headingTxt.htmlText = page.title;

            // Set the page content
            contentTxt.htmlText = page.content;
            contentRTopTxt.htmlText = page.contenttr;
            contentRBottomTxt.htmlText = page.contentbr;

            // Exit the loop
            break;
        }
    } // < /For Loop >

    } // < /If Statement >
} // < /Function >

My xml file looks somewhat like this (it's long, so I'll post a partial):

<?xml version="1.0" encoding="utf-8"?>
<site>

    <!--<sitetitle><![CDATA[<strong>Transplant the Heart</strong>]]></sitetitle>-->

    <pages>

        <page pagenumber="1">

            <title><![CDATA[<h1>Page #1</h1>]]></title>

            <content><![CDATA[<p>Aliquam nec dui neque. Aenean rutrum suscipit turpis vel fringilla. </p>]]></content>

            <contenttr><![CDATA[Cras non risus nisi. Nam tincidunt lacinia massa, vel interdum massa ultricies.]]></contenttr>

            <contentbr><![CDATA[Aliquam erat volutpat. Etiam eget mauris ante, sit amet placerat tortor.]]></contentbr>

            <image>imgs/png/titleLarge.png</image>

            <swfURL>transplantSpecialists.swf</swfURL>

        </page>

    </pages>

</site>

Are you sure you have the correct structure? Something like this ...

project folder
  | main.swf
  | scripts/
    | xml/
      | content.xml
  | imgs/
    | png/
      | titleLarge.png
  | transplantSpecialists.swf
