320 Working with XML

var loader:URLLoader = event.target as URLLoader;

if (loader != null)

{

externalXML = new XML(loader.data);

trace(externalXML.toXMLString());

}

else

{

trace("loader is not a URLLoader!");

}

To read XML data from a socket connection, use the XMLSocket class. For more

information, see the XMLSocket entry in the ActionScript 3.0 Language Reference.

Assembling and transforming XML

objects

Use the prependChild() method or the appendChild() method to add a property to the

beginning or end of an XML object’s list of properties, as the following example shows:

var x1:XML = Line 1

var x2:XML = Line 2

var x:XML = <body></body>

x = x.appendChild(x1);

x = x.appendChild(x2);

x = x.prependChild(Line 0);

// x == <body>Line 0Line 1Line 2</body>

Use the insertChildBefore() method or the insertChildAfter() method to add a

property before or after a specified property, as follows:

var x:XML =

<body>

Paragraph 1

Paragraph 2

</body>

var newNode:XML = Paragraph 1.5

x = x.insertChildAfter(x.p[0], newNode)

x = x.insertChildBefore(x.p[2], Paragraph 1.75)
