Below is a sample app that uses labelFunction to access nested xml node
values.
Also note the dataProvider specification:
dataProvider="{gXMLDoc.firstChild.childNodes}". DataGrids want an array
as a dataProvider, childNodes provides one.

Subject: [flexcoders] display nested xml in a datagrid
Hi. Can someone help with this question? It is driving me crazy!
(the entire example is at the bottom of this post)
There is more to this problem but I have tried to simplify it to the
basic question below:
Say I have the following xml:
<?xml version="1.0" encoding="UTF-8"?>
<Items>
<Item Id="1" Title="Title1">
<Status Id="1" Name="Active" />
</Item>
<Item Id="2" Title="Title2">
<Status Id="2" Name="Inactive" />
</Item>
</Items>
How can I display the current status name of each item in a data
grid?
I have tried:
<mx:DataGrid id="gridStory" dataProvider="{mx.utils.ArrayUtil.toArray
( GetItems.result.Items.Item)}" width="100%" height="100%">
<mx:columns>
<mx:Array>
<mx:DataGridColumn columnName="Id" />
<mx:DataGridColumn columnName="Title" />
<mx:DataGridColumn columnName="Status" /> shows object
Object - I want the item's Status.Name to appear
<mx:DataGridColumn columnName="Status.Name" /> **** THIS
DOES NOT WORK ****
</mx:Array>
</mx:columns>
</mx:DataGrid>
How can I show the status? If I just use
<mx:DataGridColumn columnName="Status" />
the grid displays (as expected) object Object. Also, for this
particular xml file it is not an option to just collapse the Status
subtags into the Item tag and have something like:
<Item Id="2" Title="Title2" StatusId="2" StatusName="Inactive" />
*** For reasons outside scope of question I cannot do this ***
I know the above works correctly.
Thanks for any help with this. Below is the entire example:
test.mxml
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml";>
<mx:Model id="modItems" source="simple.xml">
</mx:Model>
<mx:DataGrid id="gridStory" dataProvider="{modItems.Item}"
width="100%" height="100%">
<mx:columns>
<mx:Array>
<mx:DataGridColumn columnName="Id" />
<mx:DataGridColumn columnName="Title" />
<mx:DataGridColumn columnName="Status" />
<mx:DataGridColumn columnName="Status.Name" />
</mx:Array>
</mx:columns>
</mx:DataGrid>
</mx:Application>
simple.xml
<?xml version="1.0" encoding="utf-8"?>
<Items>
<Item Id="1" Title="Title1">
<Status Id="1" Name="Active" />
</Item>
<Item Id="2" Title="Title2">
<Status Id="2" Name="Inactive" />
</Item>
</Items>
Thanks for any help.
