Parse XML stored in Varchar(Max) field

I need to return specific values from XML stored in a varchar(max) field in ms sql server 2008.

MyTable
TransID (PK,int,not null)
Body (varchar(max),null)

select AgreementNumber, FieldName, OldValue, NewValue from (select Body from MyTable where TransID = 1)  

Return

AgreementNumber       FieldName      OldValue          NewValue
123456789               Due Date        8/20/2011        8/26/2011
123456789               Credits Paid      99.71            99.71
.......ad infinitum

Sample XML from Body column

<?xml version="1.0"?>
<EditAgreement>
<AgreeID>1050</AgreeID>
<AgreementNumber>60101050</AgreementNumber>
<CustomerName>Blah blah</CustomerName>
<Edits>
<FieldName>Due Date</FieldName>
<OldValue>8/20/2011</OldValue>
<NewValue>8/26/2011</NewValue>
</Edits>
<Edits>
<FieldName>Credits Paid</FieldName>
<OldValue>99.71</OldValue>
<NewValue>99.71</NewValue>
</Edits>
</EditAgreement>

See code sample below.  I've used a variable to imitate your Body varchar(max) column.

First step is to convert it to the xml data type.  Then some xml functions are used to retrieve the data.

Note: you may have to adapt the data types, I've used varchar(100) everywhere.

Additional info:
XML value() method
XML nodes() method
The APPLY operator

declare @xml varchar(max) = 'Your XML Sample';

with XMLData as (
      select convert(xml, @xml) BodyXML
)
select BodyXML.value('(./EditAgreement/AgreeID)[1]', 'varchar(100)') AgreeID
      , edit.value('(./FieldName)[1]', 'varchar(100)') FieldName
      , edit.value('(./OldValue)[1]', 'varchar(100)') OldValue
      , edit.value('(./NewValue)[1]', 'varchar(100)') NewValue
from XMLData
cross apply BodyXML.nodes('/EditAgreement/Edits') t(edit)
