Getting XML children

Hello, everyone.

I'm having a bit of a problem.

There's this video chat application which I need to modify, and I'm really at a loss.

There's an XML which tells you the number of users logged on. This XML is then fed to a ScrollPane. Now, I need to get this number and feed it into a PHP.

All's fine and dandy, but when I use myXML.list.length(); it throws undefined.

The XML structure is XML > List > Viewers.


Here's the script:

Code:

---

import flash.external.ExternalInterface;


var transLang="off";
var mp3:Sound;
var mp3Control: SoundChannel = new SoundChannel();
var originalViewSize="big";
var chatIsAllowed;
var rand=0;
var userlistnumber;


userlistnumber = userlistXML.children().length();



chatText.sPane.x = -5.3;
chatText.sPane.y = -3.95;
chatText.sPane.width = 397.75;
chatText.sPane.height = 398.6;


if (themeXML.@musicPlayer!="true") {
        meniul.musicPlayerComponent.visible=false;
}
if ((themeXML.@w2w!="true")||(paramList.sessionType!="private" )) {
        myCameraComponent.visible=false;
}

function sendUserStatus(event:Event)
{
        // We will use URLRequest to post our variables to a
        // PHP file which will return variables back

        // Set the location of your PHP file
        var urlReq:URLRequest = new URLRequest("http://thenaughtyandthenice.east-wolf.com/assets/swf/userlist.php");

        // Set the method to POST
        urlReq.method = URLRequestMethod.POST;

        // Define the variables to post 
        // Here is where our username and password variables are set
        // For more variables we would add additional parameters to our urlVars variable
        var urlVars:URLVariables = new URLVariables();
        urlVars.userlist = userlistnumber;

        // Add the variables to the URLRequest;
        urlReq.data = urlVars;

        // Add the URLRequest data to a new Loader
        var loader:URLLoader = new URLLoader(urlReq);

        // Set the loader format to variables and post to the PHP
        loader.dataFormat = URLLoaderDataFormat.VARIABLES;
        loader.load(urlReq);
}

I hope someone can help me with this.

Much appreciated.

It would be more helpful if you posted a sample of the xml.
If each user is represented by a <viewer> node and all viewer nodes are within a <list> node then you want to lookup myXML.list.viewer.length()

Thank you, jAQUAN. I figured it out, eventually. I actually used myXML.list.viewer.length(), however I should've put it after the loading of the XML, not before it.


Problem solved, thank you.
