Reading repeated XML nodes

Question

Hello all,

I have an XML string that I need to tear down and process. Sorry for what may be a simple problem, but I'm new to XML processing.

Here is a sample of the XML:

<?xml version="1.0" encoding="UTF-8" ?>
<CCSMessage Type="4" Name="CustomerFetchResponse" Source="CoremaContextServer" Destination="WSA0205" UserID="LoyaltyBatch" IncludeLoyaltySummary="true" LimitLoyaltyTransactions="0" >
    <Result>
        <Status>SUCCESS</Status>
    </Result>
    <Customer CustomerID="36240">
        <CustomerID CCSID="289521" TimeStamp="2010-10-01 12:13:53">36240
        </CustomerID>
        <LoyaltySummary HouseholdID="110000036242" LoyaltyStatus="2" TotalSpend="6419.80" TotalVisits="136">
            <LoyaltyIDs>

            </OfferProgress>
        </LoyaltySummary>
    </Customer>
</CCSMessage>

I can get to the <OfferProgressTotals> level just fine with this code:

xDocument.LoadXml(XMLResponse)
doc = XElement.Parse(XMLResponse)

For Each offer As XElement In doc.Descendants("OfferProgressTotals")
    If offer.HasAttributes Then
        TempOfferID = offer.Attribute("OfferID").Value
    End If

    If TempOfferID = _OneAct._Program Then
        If offer.HasElements Then
            Console.WriteLine("Offer ID : " + offer.Attribute("OfferID").Value)
            Console.WriteLine("Eligible Date : " + offer.Element("EligibleDate").Value)
        End If
    End If
Next

As you can see in the XML, there are repeated <OfferProgressTotal> nodes, but I only want to use the ones that are under the <OfferProgressTotals> where the OfferID matches what I am looking for. I have been searching for examples for days, and have not come up with anything.

Thanks!

Here's one way using LINQ:

Dim searchstr = "9001"
doc.Descendants("OfferProgressTotals") _
    .Where(Function(x) x.HasAttributes) _
    .Where(Function(x) x.Attribute("OfferID").Value = searchstr) _
    .First(Function(x)
               Console.WriteLine("Offer ID : {0}" & vbNewLine _
                                 & "Eligible Date : {1}" & vbNewLine, _
                                 x.Attribute("OfferID").Value, _
                                 x.Element("EligibleDate").Value)
               Return True
           End Function) _
    .Descendants("OfferProgressTotal") _
    .ToList _
    .ForEach(Sub(x)
                 Console.WriteLine("ID : {0}" & vbNewLine _
                                   & "Description : {1}" & vbNewLine _
                                   & "Lifetime Value : {2}" & vbNewLine, _
                                   x.Attribute("ID").Value, _
                                   x.Attribute("Description").Value, _
                                   x.Element("LifetimeValue").Value)
             End Sub)

This will output the info you showed for the parent node then the info for the childnodes that you said you wanted

With a bit of massaging, this was the PERFECT answer to what I needed to do. Many thanks!
