Setting selectedIndex via XML

Question

I have a comboBox that is populated by an XML file. Is there
a way to set the selectedIndex to a variable within the XML file?
For example, my XML data looks like this:
<villa name="Villa 2" URL="
http://www.URL2.com"
default_index="1"/>
When someone makes a selection from the combo box, I would
like the user to be directed to a new page with the default index
set correctly. In the above example, if the user chooses "Villa 2"
they are directed to the URL.com site, and I want the default in
the combo box on the new page to be index 1, which is "Villa 2".
I can successfully pass the info for the default_index via
FlashVars on the new page, but I want to set the index with the XML
file and not the HTML file.
The following line works if I set the default_index variable
through FlashVars, but doesn't read it if the default_index is set
in the XML.
comboBox.selectedIndex=default_index
Any ideas?
Here's the code that populates the comboBox and sets the
default index:
var myData:XML = new XML ();
myData.ignoreWhite = true;
myData.load ("myData.xml");
myData.onLoad = function (success:Boolean):Void
if (success)
var data:XMLNode = this.firstChild;
var children:Array = data.childNodes;
var numItems:Number = children.length;
for (var i:Number = 0; i < numItems; i++)
var child:XMLNode = children
var name:String = child.attributes.name;
var URL:String = child.attributes.URL;
comboBox.addItem (name,URL);
}comboBox.selectedIndex=default_indx
Thanks in advance!

Answer 1

for (var i:Number = 0; i < numItems; i++)
var child:XMLNode = children
var name:String = child.attributes.name;
var URL:String = child.attributes.URL;
comboBox.addItem (name,URL);
// assumes there will be only one node with a default_index
attribute
// -- if more than one, the last one will be the selected
item
if(child.attributes["default_index"] !=
undefined){comboBox.selectedIndex=i;}
other approach:
<datanode default_index="1"/>
<villa name="Villa 1" URL="
http://www.URL1.com" />
<villa name="Villa 2" URL="
http://www.URL2.com" />
<villa name="Villa 3" URL="
http://www.URL3.com" />
</datanode>
var data:XMLNode = this.firstChild;
var children:Array = data.childNodes;
var numItems:Number = children.length;
for (var i:Number = 0; i < numItems; i++)
var child:XMLNode = children;
var name:String = child.attributes.name;
var URL:String = child.attributes.URL;
comboBox.addItem (name,URL);
defIdx = Number(data.attributes["default_index"]);
comboBox..selectedIndex = isNaN(defIdx) ? 0 : defIdx;
