Passing XML data to flash

programming flash
1

I have some XML data and I would like to do a few things with it. I have a datagrid with a master list of materials and a combobox with the names the materials. I want to do a few things, load up variables depending on what name I select in the combobox. If I select a material i would like to load up the corosponding variables for that xml item so I can work with them. If i select a certian material then the width height and cost for that item are loaded into variables to calculate.

I also would like to have multiple comboboxes read from the same xml file and filter out information based on type. I want to use this one list to feed multiple data points. So if i have two combo boxes I would like one of them to be fed information but only from a particular type. Any help with this?


import fl.controls.DataGrid; 
import fl.controls.dataGridClasses.DataGridColumn; 
import fl.data.DataProvider; 
import fl.controls.ScrollPolicy; 


master.addColumn("Material");
master.addColumn("Type");
master.addColumn("Width");
master.addColumn("Length");
master.addColumn("Cost");
 
var materialsXML:XML;
var loader:URLLoader = new URLLoader(new URLRequest("master_materials.xml"));
loader.addEventListener(Event.COMPLETE, onLoaded);


function onLoaded(e:Event):void
{
    materialsXML = new XML(e.target.data);
    var xml:XML= new XML(loader.data);
    var itemList:XMLList= xml..item;
    var len:int=itemList.length();
    for(var i:int=0; i<len; i++)
    {
        material_cb.addItem( { label: materialsXML.item.name*} );
        master.addItem({Material:itemList*.name,
                    Width:itemList*.wide,
                    Length:itemList*.long,
                    Cost:itemList*.cost,
                    Type:itemList*.type});


    }
    
}


master.columns[0].width = 100; 
master.columns[1].width = 60; 
master.columns[2].width = 20; 
master.columns[3].width = 20; 
master.columns[4].width = 20;
