Create XML using variables (dynamically)

Question

Ive searched and so far not finding results. Can you create an xml file dynamically in AS3.
public class XmlWriter extends MovieClip{
private var myXMLRoot:String;
public function XmlWriter(xmlRootName:String){
myXMLRoot = xmlRootName
public writeXML():{
var temp:XML = new XML(<xmlRootName></xmlRootName> ) //where xmlRootName is the string set when the class is created
is the above possible? If so how would you do it?

Answer 1

var nodeName:String = "myNodeName";
var attributeName:String = "myAttributeName";
var attributeValue:String = "myAttributeValue";
var xml:XML = <{nodeName} {attributeName}={attributeValue} />;
trace(xml.toXMLString());
// output: <myNodeName myAttributeName="myAttributeValue"/>
