Example ( How to use this example )

The following example returns the name of the attribute:

var xml:XML=<example id='123' color='blue'/>
trace(xml.attributes()[1].name()); //color

This example returns the names of all the attributes:

var xml:XML = <example id='123' color='blue'/>
var attNamesList:XMLList = xml.@*;

trace (attNamesList is XMLList); // true
trace (attNamesList.length()); // 2

for (var i:int = 0; i < attNamesList.length(); i++)
{ 
    trace (typeof (attNamesList[i])); // xml
    trace (attNamesList[i].nodeKind()); // attribute
    trace (attNamesList[i].name()); // id and color
}
