looping through xml (newbie question)

[annelie]

Hello,

I'm having some problems looping through my xml and getting the right values. If I've understood it correctly, this should give you every Line node in the xml document:

var xmlLines:XMLList = myXmlList..Line;

This returns nothing though, so I'm doing something wrong.

Here's the xml code:

Here's the Flex code, I'm cheating a little bit to get to some of the line nodes, but ideally I would just like to be able to go through it all and call the relevant functions depending on what it is.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
initialize="initializeHandler()">

<mx:Script>
<![CDATA[
import mx.events.IndexChangedEvent;
import mx.core.UIComponent;
import mx.containers.VBox;

import components.DrawScore;

public var myXmlList:XMLList;

private function initializeHandler():void
{
var measure:DrawScore = new DrawScore();
var uic:UIComponent = new UIComponent();

myXmlList = scoreXml.children();

for (var i:uint = 0; i < myXmlList.length(); i++)
{
// isn't this supposed to give me all line nodes?
var xmlLines:XMLList = myXmlList..Line;

var canvasList:XMLList = myXmlList[i].children();

for (var iCanvas:uint = 0; iCanvas < canvasList.length(); iCanvas++)
{
// need another way to check if it's a canvas or a line (or a glyph), plus checking them for complexcontent
if (canvasList[iCanvas].hasComplexContent() == true)
{
// this is a canvas
}
else
{
// this is a line
var startX:int = canvasList[iCanvas].attribute("X1");
var startY:int = canvasList[iCanvas].attribute("Y1");
var endX:int = canvasList[iCanvas].attribute("X2");
var endY:int = canvasList[iCanvas].attribute("Y2");
var strokeColour:String = "Black";
var strokeThickness:int = canvasList[iCanvas].attribute("StrokeThickness");
var xmlNameSpace:String = canvasList[iCanvas].attribute("xmlns");

measure.createLine(startX, startY, endX, endY, strokeColour, strokeThickness, xmlNameSpace);
}
}

uic.addChild(measure);
}

var verticalBox:VBox = new VBox();
verticalBox.addChild(uic);
addChild(verticalBox);
}

]]>
</mx:Script>

<mx:XML id="scoreXml" source="assets/scoreCanvas.xml" />

</mx:Application>


I want to be able to call createLine for every line node, so if I can't use the code above, is there any other way of getting to it?

Many thanks,

Annelie

Brilliant, thank you! I used the code in the entry below that to strip out the namespaces, have no need for them so that was a better solution.

Cheers,
