XMLNode Class

internal superclass of the XML class

Flash 5 (undocumented)

Description

The XMLNode class defines the core properties and methods of nodes in an XML object

hierarchy. Though XMLNode is internal to ActionScript, it can be used by programmers to

add to the default functionality of XML objects.

Technically, every XML object hierarchy includes two kinds of object nodes:

• One XML node, which serves as the main container for the hierarchy

• An arbitrary number of XMLNode nodes, which are the children of the main con-

tainer node

The main container node is an instance of the XML class. For example, if we create

myDoc

as follows:

myDoc = new XML();

then myDoc is an instance of the XML class. The XML class inherits from the XMLNode

class, so main container nodes have all the properties and methods defined by XMLNode

plus those defined by XML. In contrast, the children of

myDoc will actually be instances of

the XMLNode class, not the XML ...
