Integrating XML into JavaScript

ExtendScript defines the XML object, which allows you to process XML with your JavaScript scripts. This

feature offers a subset of the functionality specified by the ECMA-357 specification (E4X). For more

information on this standard, see:

http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-357.pdf

The XML Object

The XML object represents an XML element node in an XML tree. The topmost XML object for an XML file

represents the root node. It acts as a list, which contains additional

XML objects for each element. These in

turn contain

XML objects for their own member elements, and so on.

The child elements of an element tree are available as properties of the

XML object for the parent. The

name of the property corresponds to the name of the element. Each property contains an array of

XML

objects, each of which represents one element of the named type.

For example, suppose you have the following, minimal XML code:

</elementA>

</elementA>

</rootElement>

In a JavaScript script, the XML object that you create from this XML code represents the root element:

var myRoot = new XML ( "<rootElement> <elementA> <elementB></elementB> </elementA>

</rootElement>");

You can assign a constant to an XML value directly. The following implicitly creates the XML object

assigned to

myRoot:

var myRoot = <rootElement>

</elementA>

</elementA>

</rootElement> ;

The object myRoot contains a property named elementA, which contains two XML objects for the two

instances of that element. Each of these, in turn, contains an

elementB property, which contains one

empty

XML object:

var elemB1 = myRoot.elementA[0].elementB[0];
