The local name of the QName object.

The Uniform Resource Identifier (URI) of the QName object.

Creates a QName object that is a copy of another QName object. If the parameter passed to the constructor is a QName object, a copy of the QName object is created. If the parameter is not a QName object, the parameter is converted to a string and assigned to the localName property of the new QName instance. If the parameter is undefined or unspecified, a new QName object is created with the localName property set to the empty string.

Note: This class shows two constructor entries because each form accepts different parameters. The constructor behaves differently depending on the type and number of parameters passed, as detailed in each entry. ActionSript 3.0 does not support method or constructor overloading.

Creates a QName object with a URI object from a Namespace object and a localName from a QName object. If either parameter is not the expected data type, the parameter is converted to a string and assigned to the corresponding property of the new QName object. For example, if both parameters are strings, a new QName object is returned with a uri property set to the first parameter and a localName property set to the second parameter. In other words, the following permutations, along with many others, are valid forms of the constructor:

QName (uri:Namespace, localName:String);
QName (uri:String, localName: QName);
QName (uri:String, localName: String);

If you pass null for the uri parameter, the uri property of the new QName object is set to null.

Note: This class shows two constructor entries because each form accepts different parameters. The constructor behaves differently depending on the type and number of parameters passed, as detailed in each entry. ActionSript 3.0 does not support method or constructor overloading.

Returns a string composed of the URI, and the local name for the QName object, separated by "::".

The format depends on the uri property of the QName object:

If uri == "" 
		toString returns localName
	else if uri == null
		toString returns *::localName 
	else
		toString returns uri::localName

Returns the QName object.

1. Creating a Namespace instance and then using it as input to the QName constructor. This approach is best if you want to use the Namespace.prefix property for other purposes later.
2. Creating a QName instance using a simple string value for the uri parameter in the QName constructor.

This code does the following things:

1. Defines an XML variable named rssXML.
2. Creates a new Namespace object with the prefix dc.
3. Creates a new QName object using the Namespace object and the local name creator.
4. Calls the showDescendants() method, which uses the XML.descendants() method to get an XMLList instance containing all the descendant elements whose qualified name matches the given QName instance.
5. Displays the qualified name and the text value of each element in the list using a for each loop.
6. Creates another QName object using a string value for the uri parameter and the local name date.
7. Calls the showDescendants() method again to display the name and text value of the descendant elements.
