@ sign? I don't think that's common in XML, unless its use is dictated
by somebody else.
Also, there's no point in building up an XML string with the + operator.
You can use "XML literal" syntax in AS3:
private var gXMLDoc:XML =
<records>
<record>
...
</records>;

Subject: RE: [flexcoders] Re: How to populate an attribute value in
DataGrid control?
First, the sample xml in your post is not valid: the data nodes have no
closing taqs (or "/"). If we fix that then the example below works for
your xml.
The key is to use the "attribute" method instead of the "@" symbol to
reference the attributes.

control?
Tracy,
Thanks for the feedback.
Unfortunately I cannot change the XML, the data is from third party
provider. I tried it with labelFunction and @@, it does not work :-(
var sFirstName:String = xmlRecord.data[0].(@@name ==
"lastname").@@value;
