Parsing XML with LINQ To XML and VB.NET

[PsychoCoder]

I'm working on parsing XML returned from a web service call. This is a sample of the returned XML (the actually result is much larger):

?xml version="1.0" encoding="utf-16"?>
<HotelPropertyDescriptionRS xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" TimeStamp="2013-12-30T18:49:36" Version="1.14.1">
  <Success xmlns="http://webservices.sabre.com/sabreXML/2003/07" />
  <RoomStay xmlns="http://webservices.sabre.com/sabreXML/2003/07">
    <RoomRates>
      <RoomRate GuaranteeSurchargeRequired="G" IATACharacteristicIdentification="BGGO00" IATAProductIdentification="BLOOMBERG" RPH="001">
        <AdditionalInfo>
          <CancelPolicy Numeric="06" />
          <Commission NonCommission="true">NON COMMISSIONABLE</Commission>
          <Text>BLOOMBERG LP, 0.0 KM, INCLUDES BREAKFAST, INTERNET, WIFI, SEE</Text>
          <Text>RATE RULES DELUXE ROOM, GUEST ROOM, 1 KING OR 2 TWIN/SINGLE BE</Text>
        </AdditionalInfo>
        <Rates>
          <Rate Amount="66.600" CurrencyCode="KWD">
            <AdditionalGuestAmounts>
              <AdditionalGuestAmount MaxExtraPersonsAllowed="0">
                <Charges ExtraPerson="0" />
              </AdditionalGuestAmount>
            </AdditionalGuestAmounts>
            <HotelTotalPricing Amount="76.590">
              <Disclaimer>INCLUDES TAXES AND SURCHARGES</Disclaimer>
              <TotalSurcharges Amount="9.990" />
            </HotelTotalPricing>
          </Rate>
        </Rates>
      </RoomRate>
...

I am attempting to parse it into this class

Namespace Classes.Models
    Public Class RoomRate
        Public Property Rate() As String
        Public Property Surcharge() As String
        Public Property TotalPrice() As String
        Public Property CurrencyCode() As String
        Public Property CancellationPolicy() As String
        Public Property Disclaimer() As String
        Public Property Text() As List(Of String)
        Public Property Commission() As String
        Public Property GuaranteeSurchargeRequired() As String
        Public Property IATACharacteristicIdentification() As String
        Public Property IATAProductIdentification() As String
        Public Property RPH() As String
    End Class
End Namespace

I have this function which should accomplish this:

Public Function ParseRates() As IEnumerable(Of RoomRate)
    Try
        Return From el As XElement In _xDoc...<RoomRate>
                    Select New RoomRate With { _
                       .GuaranteeSurchargeRequired = el.@GuaranteeSurchargeRequired, _
                       .IATACharacteristicIdentification = el.@IATACharacteristicIdentification, _
                       .IATAProductIdentification = el.@IATAProductIdentification, _
                       .RPH = el.@RPH, _
                       .CancellationPolicy = el...<AdditionalInfo>...<CancellationPolicy>.@Numeric, _
                       .Commission = el...<AdditionalInfo>...<Commission>.@NonCommission, _
                       .Rate = el...<Rates>...<Rate>.@Amount, _
                       .CurrencyCode = el...<Rates>...<Rate>.@CurrencyCode, _
                       .TotalPrice = el...<Rates>...<Rate>...<HotelTotalPricing>.@Amount, _
                       .Surcharge = el...<Rates>...<Rate>...<TotalSurchjarges>.@Amount}
    Catch ex As Exception
        ErrorMessage = ex.Message
        Return Nothing
    End Try
End Function

Then when I try and test it with this test page (page load event):

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Dim parse As New ParseSabre(Server.MapPath("~/XML/SabreSample.xml"))
    Dim rates As IEnumerable(Of RoomRate)()
 
    rates = parse.ParseRates()
 
    'If rates = Nothing Then
 
    'End If
    For Each rate As RoomRate In rates
        Response.Write(rate.GuaranteeSurchargeRequired)
        Response.Write(rate.IATACharacteristicIdentification)
        Response.Write(rate.IATAProductIdentification)
        Response.Write(rate.RPH)
        Response.Write(rate.CancellationPolicy)
        Response.Write(rate.Commission)
        Response.Write(rate.Rate)
        Response.Write(rate.CurrencyCode)
        Response.Write(rate.TotalPrice)
        Response.Write(rate.Surcharge)
        Response.Write(vbNewLine)
    Next
End Sub

I get the following error

Unable to cast object of type 'WhereSelectEnumerableIterator`2[System.Xml.Linq.XElement,Lodgx.Classes.Models.Room Rate]' to type 'System.Collections.Generic.IEnumerable`1[Lodgx.Classes.Models.RoomRate][]'.

Can someone tell me

1. Is my code for parsing going to accomplish what I'm looking for?
2. How can I get rid of that error so I can continue to test this?

[PsychoCoder]

I have changed my code to look like so. I get no error but no values are returned:

For Each n As XElement In _xDoc.Descendants("RoomRate")
    rate = New RoomRate()
    rate.GuaranteeSurchargeRequired = n.Attribute("GuaranteeSurchargeRequired").Value
    rate.IATACharacteristicIdentification = n.Attribute("IATACharacteristicIdentification").Value
    rate.IATAProductIdentification = n.Attribute("IATAProductIdentification")
 
    _rates.Add(rate)
