    XML length & for-each

    I have 10 dynamic text fields inside a movieclip, which are populated via an XML file. However, the xml file sometimes has less than 10 items. It never has more than 10. This results in the following error, which is normal. I need the code to count the amount of items in the XML file and then create a for-each loop. I can visualize it, but I don't know how to write it.

    Basically what I need the code below transformed in to is this... (notice the #'s)

    (count xml items)

    for each item {
    pb_mc.pb_#.htmlText="<b>MyContent:</b> "+updates.m[#].text();

    TypeError: Error #1010: A term is undefined and has no properties.
    at mycontent_fla::MainTimeline/showXML()
    at flash.events::EventDispatcher/dispatchEventFunction()
    at flash.events::EventDispatcher/dispatchEvent()
    at flash.net::URLLoader/onComplete()

    <?xml version="1.0"?>
    	<m>Blah blah blah my content text goes here and shows up in the first dynamic text field.</m>
    	<m>Blah blah blah....this would be the second dynamic text field... and so on</m>
    xmlLoader.addEventListener(Event.COMPLETE, showXML);

    function getMyContent() {
    xmlLoader.load(new URLRequest("http://www.mysite.com/myDynamicXML.xml"));

    function showXML(e:Event):void {
    var updates:XML=new XML(e.target.data);
    pb_mc.pb_1.htmlText="<b>MyContent:</b> "+updates.m[0].text();
    pb_mc.pb_2.htmlText="<b>MyContent:</b> "+updates.m[1].text();
    pb_mc.pb_3.htmlText="<b>MyContent:</b> "+updates.m[2].text();
    pb_mc.pb_4.htmlText="<b>MyContent:</b> "+updates.m[3].text();
    pb_mc.pb_5.htmlText="<b>MyContent:</b> "+updates.m[4].text();
    pb_mc.pb_6.htmlText="<b>MyContent:</b> "+updates.m[5].text();
    pb_mc.pb_7.htmlText="<b>MyContent:</b> "+updates.m[6].text();
    pb_mc.pb_8.htmlText="<b>MyContent:</b> "+updates.m[7].text();
    pb_mc.pb_9.htmlText="<b>MyContent:</b> "+updates.m[8].text();
    pb_mc.pb_10.htmlText="<b>MyContent:</b> "+updates.m[9].text();

    setInterval(getMyContent, 60000);// 60 sec

    Here's how I would do it...

    PHP Code:
    private function showXML(e:Event):void
    updates:XML = new XML(e.target.data);
        var list:
    XMLList = new XMLList(updates.m);
        for (var 
    i in list){
    trace(i+': '+list[i]);
    pb_mc['pb_'+(Number(i)+1)].htmlText '<b>MyContent: </b>'+list[i];

    1) Create a loader object

    Thinking outside of the box will get you fired if the "box" is strict budget.

    oh yeah, the loop above will run through the entire list, but if you need to know how many items there then just call list.length()
