E4X means "ECMAScript For XML Using E4X, we can develop code with XML data faster than was possible with previous programming techniques. E4X provides a set of classes and functionality for working with XML data. ActionScript 3.0 includes the following E4X classes: XML, XMLList, QName, and Namespace.
Here is an example of manipulating data with E4X:
var myXML:XML = <order> <item id="1"> <name>colddrink</name> <price>12</price> < /item> <item id="2"> <name>burger</name> <price>10</price> < /item> < /order> trace (myXML.item.menuName); // Output: colddrink trace (myXML.item.(@id==2).menuName); // Output: burger trace (myXML.item.(menuName=="burger").price); // Output: 10
