AdvancedDataGrid with XMLListCollection Syntax

Question

Hello All,
I'm more of an XSLT/XPath guy, and need help with the syntax
for Flex(if that's the only thing I'm doing wrong!). I have an
XMLListCollection named "mapData" with records from a web service.
Each record looks like this:
<java:Results xmlns:java="java:com.example.com">
<java:AssociatedFileID>9999</java:AssociatedFileID>
<java:AssociatedFileName>example.csv</java:AssociatedFileName>
<java:DataBucketID>123</java:DataBucketID>
<java:DataBucketName>EDashboard</java:DataBucketName>
<java:Fields>
<java:DataBucketFieldName>Business</java:DataBucketFieldName>
<java:DataBucketFieldValue>Loans</java:DataBucketFieldValue>
<java:DataBucketFieldID>4281</java:DataBucketFieldID>
</java:Fields>
<java:Fields>
<java:DataBucketFieldName>Section</java:DataBucketFieldName>
<java:DataBucketFieldValue>Europe</java:DataBucketFieldValue>
<java:DataBucketFieldID>4394</java:DataBucketFieldID>
</java:Fields>
<java:LoadedDateTime>2008-03-19T10:57:21-04:00</java:LoadedDateTime>
<java:Suppressed>No</java:Suppressed>
<java:DataBucketContentID>170</java:DataBucketContentID>
<java:Status>Active</java:Status>
</java:Results>
My AdvancedDataGrid is:
<mx:AdvancedDataGrid x="10" y="10" id="MapDG"
designViewDataType="flat" width="100%" height="100%"
dataProvider="{mapData}" click="{editBtn.enabled=true;}"
selectionMode="singleRow" change="{editBtn.enabled=true;}">
<mx:columns>
<mx:AdvancedDataGridColumn headerText="ID"
dataField=""/>
<mx:AdvancedDataGridColumn headerText="Business"
dataField=""/>
<mx:AdvancedDataGridColumn headerText="Section"
dataField=""/>
</mx:columns>
</mx:AdvancedDataGrid>
Here's what I'm trying to do for each column:
1 - *::Results.*::DataBucketContentID.text()
//this is the record ID
2. -
*Results.*::Fields.(*::DataBucketFieldName.text()='Business').*DataBucketFieldValue.text( )
//Gets the 'DataBucketFieldValue' for each 'Fields' that has
a 'DataBucketFieldName' = Business
3. -
*Results.*::Fields.(*::DataBucketFieldName.text()='Section').*DataBucketFieldValue.text()
//Gets the 'DataBucketFieldValue' for each 'Fields' that has
a 'DataBucketFieldName' = Section
What do I need to put in the columns' dataField for this to
work?
Thanks,
Trav

Thanks to Tracy and a little research, I have my data grid
populating - I wanted to post an example that worked for me:
If below is a variable with your web service result...
private var personXML:XML=<persons>
<person>
<FirstName>Santa</FirstName>
<Surname>Claus</Surname>
<Age>1000</Age>
</person>
<person>
<FirstName>Tooth</FirstName>
<Surname>Fairy</Surname>
<Age>250</Age>
</person>
<person>
<FirstName>Travis</FirstName>
<Surname>Allen</Surname>
<Age>27</Age>
</person>
</persons>
You can use a function, which you'll need to assign to a
column. Here it is concating text in 2 elements but you can also
use it for namespaced elements (e.g.
item.*::NodeName1.*::NodeName2.text()).
private function showFullName(item:Object,
Column:DataGridColumn):String{
var fullName:String = item.FirstName + " " + item.Surname;
return fullName;
The first column uses the function to populate the data in
the column. It has to use labelFunction (vs. dataField). The 2nd
uses the node name directly.
<mx:DataGrid id="personDG"
dataprovider="{personXML.person}">
<mx:columns>
<mx:DataGridColumn width="150" headerText="Full Name"
labelFunction="showFullName"/>
<mx:DataGridColumn width="150" dataField="Age"
width="50"/>
<!--the column without header text wil take the value of
the element-->
</mx:columns>
</mx:DataGrid>
Hope this helps anyone else!
