XML2Object revisited

Alessandro Crugnola actionscript , , ,

An XML2Object revisited class.
Basically it works in the same ways as the previius one, but now in the parseXML method it can be defined a 2nd parameter which will tell to the parser to put all xml nodes into arrays. In this way all variables created into the returned object will be stored into array. for example:

import it.sephiroth.XMLObject;
myxml.onLoad = function(){
     	var data = new XMLObject().parseXML( this, true );
}

The second addition to this class is the parseObject method, which will convert any object into an xml. for example, this code:

import it.sephiroth.XMLObject;
myobject = {
   	attributes : {
    		name : "custom object",
    		type : 1   	},
   	item : [   { name : "Varese", code : "VA" },   { name : "Milano", code : "MI" }  ],
   	channel : {   name : "City",   country : "Italy"  } }
data = new XMLObject().parseObject(myobject,"TEST");

will produce this xml string:

<?xml version="1.0"?> 	<TEST type="1" name="custom object"> 		<item> 			<name>Varese</name> 			<code>VA</code> 		</item>   		<item>    			<name>Milano</name>    			<code>MI</code>   		</item>   		<channel>    			<name>City</name>    			<country>Italy</country>   		</channel>  	</TEST>

And here’s the class code: XMLObject.as

XML2Object

Alessandro Crugnola actionscript ,

This class, that is just a translation of a simple set of function written for Flash MX, translates any kind of XML document into a readable Flash Object. This could be the core for projects XML oriented..
in fact i work often on xml based projects… 

/**
* @class it.sephiroth.XML2Object
* @author Alessandro Crugnola
* @version 1.0
* @description return an object with the content of the XML translated
* NOTE: a node name with "-" will be replaced with "_" for flash compatibility.
* for example  will become FIRST_NAME
* If a node has more than 1 child with the same name, an array is created with the children contents
* The object created will have this structure:

* 	- obj {

*		nodeName : {

*			attributes : an object containing the node attributes

*			data : an object containing the node contents

*	}

* @usage data = new XML2Object().parseXML( anXML);

An Example usage with this file:
http://www.sephiroth.it/tutorials/flashPHP/indice.xml

import it.sephiroth.XML2Object;
var oXML:XML = new XML ();
var sXML:String = "indice.xml";
oXML.ignoreWhite = true;
function xmlLoaded (success:Boolean) {
        if (success) {
                trace (success);
                _root.ObjFromXML = new XML2Object ().parseXML (this);
                delete this
        }
}
oXML.onLoad = xmlLoaded;
oXML.load (sXML);
