Flex + XML + dataProvider : Problem specifying dataProvider to ComboBox & DataGrid

I get a XML Response from a PHP Script which I access using [lastResult] property.

The problem is the follwing:

XML Structure:

<Main>
  <Category1>
    <Data Name="Data1">
      <Item>
        <Name>foo</Name>
        <Info>bar</Info>
      </Item>
      <Item>
        <Name>baz</Name>
        <Info>FOO</Info>
      </Item>
    </Data开发者_开发技巧>
    <Data Name="Data2">
    </Data>
  </Category1>
  <Category2>
    </Category2>
</Main>

Now I specify the dataProvider for the DataGrid as

'lastResult.Category1.Data.(@Name == "Data1").Item'

This works fine enough & my data is correctly outputted. The only thing I need is that how can I access the @Name property of the <Data> tag.

I can output Name & Info of Items by specifying:

'Name'
'Info'

But I'm clueless how to specify the @Name attribute of the parent <Data> tag when I've selected Data.Item as the dataProvider.

From what I can make of it, I need to go up 1 level to the parent node, but I couldn't find any reference so as how to go up one level while using [lastResult] dataProvider (all were using XMLListCollection::parent())

Any help is appreciated.

lastResult.Category1.Data.(@Name == "Data1").Item gives you XMLList of Items found in Data1. Each item is of type XML and you can call parent() function get parent node:

//get first item
var item:XML = lastResult.Category1.Data.(@Name == "Data1").Item[0];
trace("Data.@Name: " + item.parent().@Name);

Edit: to make it work inside DataGrid, you need to use labelFunction property of column. Set it to this:

function formatItem(item:Object, column:DataGridColumn):String {
    return (item as XML).parent().@Name;
}
