XMLSocket

Even in ActionScript, building client-side socket software is not terribly difficult. Remember that ActionScript has two different objects, XML and XMLSocket. These are entirely distinct. An XML object is a data package. It has many properties and many methods, but they all deal with a tree of data that is organized along the principles of XML and that can translate itself from string representation to data object and back with great reliability.

An XMLSocket is not a data interface at all; it is a communications interface. The operative word is “socket,” and its methods are similar to the socket function in PHP, Perl or Unix.
