Populating Radgrid with xml document

[Henry]

I am having trouble reading this xml file into Telerik  Ajax RadGrid. The problem is that the xml file is in a weird format that Telerik does not seem to recognize.  Here is an example from the xml file that I want to read into my grid. Does anyone have any suggestions? Thanks
 

<Attribute>
     <Object>
         <Id>27</Id>
         <Type>212</Type>
    </Object>
   <AttributeDef>
        <Id>38</Id>
  </AttributeDef>
  <RowId>0</RowId>
  <StringValue/>
  <DecimalValue xsi:nil="true"/>
  <DateTimeValue xsi:nil="true"/>
  <LongStringValue/>
  <IsLinked>Y</IsLinked>
  <MayModify>Y</MayModify>
  <ValueDescription/>
</Attribute>

I'd use XPath navigator to massage the data to a format that the grid will process
