Two things come to mind:

You can set the result type to object and let HTTPService to the heavy lifting of converting XML to Objects for you:

http://blog.flexexamples.com/2007/09/19/converting-xml-to-objects-usin g-the-flex-httpservice-mxml-tag/

or you receive data as XML and use SimpleXMLDecoder class to convert it into objects and add them to a ArrayCollection

Not too sure that this is the solution I need, I'm not familiar with the SimpleXMLDecoder function but it looks as if the XML data itself needs to be modelled already in order to be succesful.

I'm already a bit further on my quest to a solution, converting the content to an object does the trick indeed, at least when I hardcode it. I still am stuck on how to do this programatically / dynamic.

eg : the XMLdata is

<items name="total">
<item name="value1" percentage="35"/>
<item name="value2" percentage="25"/>
<item name="value3" percentage="47"/>
<item name="value4" percentage="89"/>
</items

and this needs to be dynamically converted to an object as follows :

var obj:Object = {name:"total", value1:35, value2:25, value3:47, value4:89}

Once I have this object the rest is simple, but I fail to do this conversion properly...

its been a year since there was any activity on this thread so, is the question answered ?

if not... you can you an intermediate array and push elements one by one inside it and the convert this array into arraycollection.

This works partiallly but it keeps all the XML Node names?? AND WHEN USED WITH A DATAGRID SEARCH iT BLOW UP IN FLEX

so help would still be nice

myData = new ArrayCollection(mx.utils.ArrayUtil.toArray(xmlStudents));

I found it on:

http://www.flexdeveloper.eu/forums/actionscript-3-0/converting-xml-to- arraycollection/

I ultimately needed it for this code examples:

Hi,

Here is the code which converts XMLList to an arraycollection...

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init();" layout="absolute">
<mx:Script>
<![CDATA[
   import mx.collections.ArrayCollection;
   import mx.rpc.xml.SimpleXMLDecoder;

   private var acAllNodes:ArrayCollection;
   private var acOpenNodes:ArrayCollection;

   private function init():void
   {
    convertXmlListToArrayCollection();
   }
   private function convertXmlListToArrayCollection():void
   {
    var strXML:String = dpNodes.toXMLString();
    strXML = "<root>" + strXML + "</root>";
    var xml:XML = new XML(strXML);
    var xmlDoc:XMLDocument = new XMLDocument(xml);
    var decoder:SimpleXMLDecoder = new SimpleXMLDecoder(true);
    var resultObj:Object = decoder.decodeXML(xmlDoc);
    acAllNodes = new ArrayCollection();

    if(resultObj.root.hasOwnProperty("items"))
    {
     if(resultObj.root.items is ArrayCollection)
     {
      acAllNodes = resultObj.root.items;
     }
     else if(resultObj.root.items is Object)
     {
      acAllNodes.addItem(resultObj.root.items);
     }
    }
   }
]]>
</mx:Script>

<mx:XMLListCollection id="dpNodes">
        <mx:source>
            <mx:XMLList>
                <items name="total">
    <item name="value1" percentage="35"/>
    <item name="value2" percentage="25"/>
    <item name="value3" percentage="47"/>
    <item name="value4" percentage="89"/>
    </items>
    <items name="somesub">
    <item name="value1" percentage="15"/>
    <item name="value2" percentage="27"/>
    <item name="value3" percentage="56"/>
    <item name="value4" percentage="43"/>
    </items>
            </mx:XMLList>
        </mx:source>
    </mx:XMLListCollection>

</mx:Application>

Bhasker,

YES your solution worked...thanks.

It does appear to be customized for each Xml document which uses different node names. Took me 5 minutes to figure out your XML Set started with "items" where as mine started with "student"...thanks.

other than it worked perfectly:

var strXML:String = xmlStudents.toXMLString();

strXML =

"<root>" + strXML + "</root>";

//Alert.show(strXML, 'Alert Box', mx.controls.Alert.OK);

var xml:XML = new XML(strXML);

var xmlDoc:XMLDocument = new XMLDocument(xml);

var decoder:SimpleXMLDecoder = new SimpleXMLDecoder(true);

var resultObj:Object = decoder.decodeXML(xmlDoc);

myData =

new ArrayCollection();

if(resultObj.root.hasOwnProperty("student"))

{

if(resultObj.root.student is ArrayCollection)

{

myData = resultObj.root.student;

}

else if(resultObj.root.student is Object)

{

myData.addItem(resultObj.root.student);

}

HERE IS MY fx:XMLLIST I based

<fx:XMLList id="xmlStudents">

<name>Christina Coenraets</name>

<email>ccoenraets@fictitious.com</email>

<image>images/arrow_icon_sm1.png</image>

</student>

</fx:XMLList>
