| Class | public final dynamic class XMLList |
| Inheritance | XMLList  Object |
| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
If an XMLList object has only one XML element, you can use the XML class methods on the
XMLList object directly. In the following example, example.two is an XMLList
object of length 1, so you can call any XML method on it.
var example2 = <example><two>2</two></example>;
If you attempt to use XML class methods with an XMLList object containing more than one XML
object, an exception is thrown; instead, iterate over the XMLList collection (using a
for each..in statement, for example) and apply the methods to each XML object in
the collection.

AS3 function toString():String| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9 |
Returns a string representation of all the XML objects in an XMLList object. The rules for this conversion depend on whether the XML object has simple content or complex content:
- If the XML object has simple content,
toString()returns the string contents of the XML object with the following stripped out: the start tag, attributes, namespace declarations, and end tag.
- If the XML object has complex content,
toString()returns an XML encoded string representing the entire XML object, including the start tag, attributes, namespace declarations, and end tag.
To return the entire XML object every time, use the toXMLString() method.
String — The string representation of the XML object.

Example ( How to use this example )
toString() method returns when the
XML object has simple content:
var test:XML = <type name="Joe">example</type>; trace(test.toString()); //example
toString() method returns when the
XML object has complex content:
var test:XML =
<type name="Joe">
<base name="Bob"></base>
example
</type>;
trace(test.toString());
// <type name="Joe">

toXMLString | () | method |
AS3 function toXMLString():String| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9 |
Returns a string representation of all the XML objects in an XMLList object.
Unlike the toString() method, the toXMLString()
method always returns the start tag, attributes,
and end tag of the XML object, regardless of whether the XML object has simple content
or complex content. (The toString() method strips out these items for XML
objects that contain simple content.)
String — The string representation of the XML object.
