[AS3] Post Trace Data to Datagrid in Flash CS4

[Trent Harris]

Hello Everyone-

I am stuck on a problem and was wondering if anyone could point me in the right direction. I have a flash swf that reads xml data. Below is the code that reads the external xml file and parses it based on user ID.

The results are correct and show in the output window. I am stuck on how to get those trace results to load into a datagrid for view. Can anyone help with this?

var myLoader:URLLoader = new URLLoader;
var xmlData = new XML();

myLoader.addEventListener(Event.COMPLETE, LoadXML);
myLoader.load(new URLRequest("XML_WIN_Data.xml"));


function LoadXML(e:Event):void {
xmlData=new XML(e.target.data);
parse(xmlData);
}

function parse(Input:XML):void {
var dataroot:XMLList=Input.XML_WIN_Data.children();
var Attributes:XMLList=Input.XML_WIN_Data.attributes() ;
var List:XMLList = Input.XML_WIN_Data.(employeeid == "0101554");
trace(List);
}

Have a look at that and see the example. They explain something about a dataprovider
and how to set the columns in the datagrid . That is how you get it into a datagrid

The site has a lot of data in it, but I am not sure were to really begin. do you know of any samples that would show how to put together the next step in moving the parsed data to the datagrid. I have tried a couple methods, but have yet to succeed.

var dp:DataProvider = new DataProvider();
var totalEntries:uint = 42;
var i:uint;
for(i=0; i<totalEntries; i++) {
    dp.addItem( {     col1:"CellName",
                    col2:"CellName",
                    col3:"CellName" } );            
}

var dg:DataGrid = new DataGrid();
dg.columns = [ "col1", "col2", "col3" ];
dg.editable = true;
dg.dataProvider = dp;
dg.move(200,10);
dg.setSize(200,300);
addChild(dg);

That is the part that creates the data and loads the datagrid. ..Modify that to suit your requirements

I was able to get closer to getting this finished with the code provided. Thank you, but i still see to get an error, below is the code:

stop()

import fl.controls.DataGrid;
import fl.data.DataProvider;

var dpataProvider;
var myDataGridataGrid = new DataGrid();
myDataGrid.addColumn("employeeid");
myDataGrid.addColumn("type");
myDataGrid.addColumn("style");
myDataGrid.addColumn("size");
myDataGrid.addColumn("length");
myDataGrid.addColumn("assigndate");
myDataGrid.setSize(200, 200);
myDataGrid.width = 575;
myDataGrid.move(20, 20);
addChild(myDataGrid);




var myLoader:URLLoader = new URLLoader;
var xmlData = new XML();


myLoader.addEventListener(Event.COMPLETE, LoadXML);
myLoader.load(new URLRequest("XML_WIN_Data.xml"));


function LoadXML(e:Event):void {
xmlData=new XML(e.target.data);
parse(xmlData);
}

function parse(Input:XML):void {
var dataroot:XMLList=Input.XML_WIN_Data.children();
var Attributes:XMLList=Input.XML_WIN_Data.attributes() ;
var List:XMLList = Input.XML_WIN_Data.(employeeid == ID);
var xmlDP:XML = new XML(List.data)

dp = new DataProvider(xmlDP);
myDataGrid.dataProvider = dp;


}


The error message i get is the following:

TypeError: Error #1088: The markup in the document following the root element must be well-formed.
at test2_fla::MainTimeline/parse()

at flash.events::EventDispatcher/dispatchEventFunction()
at flash.events::EventDispatcher/dispatchEvent()
at flash.net::URLLoader/onComplete()

Is this something to do with the var calling the outputted XML file?

What is the structure of your xml.

if XML_WIN_Data is the root node of your xml you just use Input.children.

Here is a example

function parse(Input:XML):void {
    var list = Input;
    trace("--- END 1 --- ");
    var list2 = Input.children();
    trace(list2);
    trace("---- END 2 --- ");
    var list3 = Input.employee.(@employeeid==1);
    trace(list3);
    trace("--- END 3 -- ");
    for each (var xmlT in list3){
        trace(xmlT.name);
    }
}

And the output.:: Follow the traces to see what happens
Original xml

<?xml version="1.0" encoding="utf-8"?>
<XML_WIN_Data>
<employee employeeid="1">
<name>Sonny</name>
</employee>
<employee employeeid="2">
<name>Someonelese</name>
</employee>
</XML_WIN_Data>

--- END 1 ---
<employee employeeid="1">
<name>Sonny</name>
</employee>
<employee employeeid="2">
<name>Someonelese</name>
</employee>
---- END 2 ---
<employee employeeid="1">
<name>Sonny</name>
</employee>
--- END 3 --
