ActionScript 3.0 :: Possible To Read Declaration When Loading External XML File?

When loading an external XML file into flash, is it possible to read the XML declaration and other data such as xml-stylesheet? If so, how?

XML FILE
Code: Select all<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet href="books.xsl" type="text/xsl"?>
<content>
<book>Hello</book>
</content>

AS3:
Code: Select all//Set XML calls
var xmlLoader:URLLoader = new URLLoader();
xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);
xmlLoader.load(new URLRequest("xml/books.xml"));
function xmlLoaded(e:Event):void {
var xml:XML =new XML(e.target.data);
When tracing, the XML declaration is gone, so I am not sure how to read or target it.
trace(xml);
}
