I have the following code, in an asmx file:

Public Structure ThreePartOffer
   Public startTime As DateTime
   Public endTime As DateTime
   Public expirationTime As DateTime
   Public resource As String
   Public combinedCycle As String
   Structure FipFop
       Public startTime As DateTime
       Public endTime As DateTime
       Public fippercent As Decimal
       Public foppercent As Decimal
   End Structure
   Structure StartupCost
       Public startTime As DateTime
       Public endTime As DateTime
       Public hot As Decimal
       Public inttermediate As Decimal
       Public cold As Decimal
   End Structure
   Structure MinimumEnergy
       Public startTime As DateTime
       Public endTime As DateTime
       Public cost As Decimal
   End Structure
   Public Structure EnergyOfferCurve
       Public startTime As DateTime
       Public endTime As DateTime
       Public curveStyle As String
       Public Structure CurveData
           Public xvalue As Double
           Public y1value As Double
       End Structure
       Public incExcFlag As String
   End Structure
End Structure

I am trying to make a variable, say TPO, that I can assign values to every
type under ThreePartOffer.  Is this possible?  The XML code looks like the
following:

- <ThreePartOffer>
 <startTime>2008-01-01T00:00:00-06:00</startTime>
 <endTime>2008-01-02T00:00:00-06:00</endTime>
 <expirationTime>2007-12-31T04:00:00-06:00</expirationTime>
 <resource>AcmeUnit1</resource>
 <combinedCycle>AcmeCC</combinedCycle>
   - <FipFop>
         <startTime>2008-01-01T00:00:00-06:00</startTime>
         <endTime>2008-01-02T00:00:00-06:00</endTime>
         <fipPercent>50</fipPercent>
         <fopPercent>50</fopPercent>
     </FipFop>
     - <StartupCost>
             <startTime>2008-01-01T00:00:00-06:00</startTime>
             <endTime>2008-01-02T00:00:00-06:00</endTime>
             <hot>333.33</hot>
             <intermediate>444.44</intermediate>
             <cold>666.66</cold>
       </StartupCost>
     - <MinimumEnergy>
             <startTime>2008-01-01T00:00:00-06:00</startTime>
             <endTime>2008-01-02T00:00:00-06:00</endTime>
             <cost>1001.11</cost>
       </MinimumEnergy>
     - <EnergyOfferCurve>
             <startTime>2008-01-01T00:00:00-06:00</startTime>
             <endTime>2008-01-01T10:00:00-06:00</endTime>
             <curveStyle>CURVE</curveStyle>
           - <CurveData>
                   <xvalue>60</xvalue>
                   <y1value>40.00</y1value>
             </CurveData>
           - <CurveData>
                   <xvalue>80</xvalue>
                   <y1value>45.00</y1value>
             </CurveData>
       <incExcFlag>INC</incExcFlag>
       </EnergyOfferCurve>
 </ThreePartOffer>

Or any other approaches for an asmx file.  Thank you.
