XML problem in bar chart app

[stevet26]

Hi

I am a Flash Newbie and a project has kind of been forced upon me by the powers that be. So I have been muddling through and got to a point which is really puzzling me.

Basically I have and XML file which holds monthly referrer data. Only one months worth at the mo.

<stats>
	<item>
               <year>2007</year>
               <month>March</month>
               <hitcount>7</hitcount>
               <submit>3</submit>
        </item>
</stats>

What I am trying to do is read in this data and use it to build a bar chart.

This is done by looping though the <items>, adding a movie clip to the stage and using the <hitcount> value to determine the _x value of the movie clip.

This was all going swimmingly up until it had to get the values out of the XML file. All I keep getting is either undefined messages or a null value. This is very frustrating

Here is the actionscript code I am working with

fscommand("allowscale", false);
fscommand("showmenu", false);

//Set Variables
var R_ID:String ="1";
var FilePath:String ="[URL unfurl="true"]http://localhost/";[/URL]
var myXML:XML = new XML();

//Load in the XML file
myXML.ignoreWhite = true;
myXML.onLoad = checkUpload;
myXML.load(FilePath+"XMLFile.xml");

function checkUpload(success) {
        if(success == true) {
			var i:Number;
			var root = myXML.firstChild;
				
				y_Int = 25;
				
				for (i=0; i<root.childNodes.length; i++) {
						
					_root.attachMovie("whole_bar","bar"+i, i);
					_root["bar"+i]._x = 20;
					_root["bar"+i]._y = y_Int;
									
					_root["bar"+i].bar._xscale = root.childNodes[i].childNodes[2].value;
					
					_root["bar"+i].iCount.text = root.childNodes[i].childNodes[2].value;
									
					_root["bar"+i].txtMonthName.text = root.childNodes[i].childNodes[1].value + " " + root.childNodes[i].childNodes[0].value ;
					
					y_Int += 20;
						
				} 
		} else {
			trace("Error loading XML")
			stop();
		}
}

If anyone can shed some light as to why I am unable to get these values out of the XML file it would be much appreciated.

Thanking you in advance.

It's almost there - you have to do it like this:

_root["bar"+i].bar._xscale = root.childNodes.childNodes[2].firstChild.nodeValue;

etc etc.
