Converting XML to objects using the Flex HTTPService MXML tag

mae,

I’m not sure of the *best* way, but I’ve found this works (but almost feels a little “hacky” to me):

MyCustomObject.as

package {
    import mx.utils.ObjectProxy;

    public class MyCustomObject extends Object {
        public var name:String;
        public var images:ObjectProxy;

        public static function create(value:Object):MyCustomObject {
            var co:MyCustomObject = new MyCustomObject();
            co.name = value.name;
            co.images = value.images;
            return co;
        }
    }
}

main.mxml — snippet

private function serv_result(evt:ResultEvent):void {
    var resultObj:MyCustomObject = MyCustomObject.create(evt.result.album as Object);
    /* Assign the values... */
    nameText.text = resultObj.name;
    img0Text.text = resultObj.images.image[0];
    img1Text.text = resultObj.images.image[1];
    img2Text.text = resultObj.images.image[2];
}

After a bit of Googling, this looks like it could do the trick. Darron Schall has an excellent looking example in his blog, “Convert Generic Objects into Class Instances”.

Peter,

I’m getting the following error with Darron’s code (I emailed him as well).

Error #2030: End of file was encountered.

In ByteArray/readObject()

I’m returning an object from an ASP.Net Web service.

Any ideas? My resultFormat is object.

Thanks.

Mae and Peterd,

I’m also encountering this issue… has anyone figured why this message occurs? Thanks!

Hi Peter

i read the other topic on your blog, we can use the function at the below to get the xml’s data on the data grid

private function resultHandler(event:ResultEvent):void	{
	xmlData = event.result.mynode.childnode.source as Array;
	xmlDataAC.source = xmlData;
}

but in this case the xml format is has different child node
One

image1.jpg
image2.jpg
image3.jpg

can i still use xmlData = event.result.album.name.source as Array; and
xmlData2 = event.result.album.image.source as Array; to get the data ?? i have tried that they were not work. do you have any suggestion to get the data from different node easily ?? because img0Text.text = resultObj.album.images.image[0]; is so hard to use when my xml has alot/ unknow lenght node.

Andrew,

I typically use <ComboBox>.selectedItem.<fieldName>, or, something like the following:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">

    <mx:Array id="arr">
        <mx:Object label="One" data="1" />
        <mx:Object label="Two" data="2" />
        <mx:Object label="Three" data="3" />
        <mx:Object label="Four" data="4" />
    </mx:Array>

    <mx:ComboBox id="comboBox" dataProvider="{arr}" />
    <mx:Label text="comboBox.selectedItem.label={comboBox.selectedItem.label}" />
    <mx:Label text="comboBox.selectedItem.data={comboBox.selectedItem.data}" />

</mx:Application>

Hope that helps,
Peter

to simplify what I’m saying… i want to mimic the:

    <mx:Array id="arr">
        <mx:Object label="One" data="1" />
        <mx:Object label="Two" data="2" />
        <mx:Object label="Three" data="3" />
        <mx:Object label="Four" data="4" />
    </mx:Array>

but coming from an HTTPService from a .php file outputting XML
