I have an interface that sends data to a web page (GXI.aspx) The XML Sent looks like :

<?xml version = '1.0'?>
<?Label VCAT|RESULT|54|SUCCESS?>
<RESULT xmlns="result.fidelio.1.0" success="SUCCESS">
   <resortId>VCAT</resortId>
   <resultMessage>Successfully updated profile in Opera.</resultMessage>
   <ResultIds>
      <ResultId resultMsgType="PROFILE">
         <pmsId>59020</pmsId>
         <memberNr>SI-A-P-00120</memberNr>
      </ResultId>
   </ResultIds>
</RESULT>

I need a way to...
1)  Retrieve the <?LABEL Data
2)  Get the <ResultId resultMsgType >
3)  From the <ResultId>
        <pmsId>
        <memberNr>

My code is included below.
Imports System.IO
Imports system.xml
 
Partial Class GXI
    Inherits System.Web.UI.Page
    Dim pmsId As String, memberNr As String, resultMsgType As String
    Dim OC As New OperaComplete
 
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim ER As New GXIErrors
        Page.Response.ContentType = "text/xml"
        '// Read XML posted via HTTP
        '?propertyName=VCAT&messagetype=RESULT&transactionId=50&Status=SUCCESS
        Me.Label1.Text = Request.QueryString("propertyName")
        Me.Label2.Text = Request.QueryString("messageType")
        Me.Label3.Text = Request.QueryString("transactionId")
        Me.Label4.Text = Request.QueryString("Status")
        Dim reader As StreamReader = New StreamReader(Page.Request.InputStream)
        'Dim xmlText As String = reader.ReadToEnd
        Try
            ReadXML(reader)
            If IsNumeric(pmsId) Then
                OC.NewRecord()
                OC.pmsID = CLng(pmsId)
                OC.MemberNr = memberNr
                OC.messageType = resultMsgType
                OC.TransID = CLng(Request.QueryString("transactionId"))
                OC.Save()
            Else
                ER.NewRecord()
                ER.ErrorText = "pmsId=" & pmsId & ", memberNr=" & memberNr & ", ResultMsgType=" & resultMsgType
                ER.ErrorLocation = "PageLoad"
                ER.Save()
            End If
        Catch ex As Exception
 
            ER.NewRecord()
            ER.ErrorText = ex.Message
            ER.ErrorLocation = "PageLaod"
            ER.Save()
        End Try
 
    End Sub
    Private Sub ReadXML(ByVal inReader As StreamReader)
        Try
            Dim m_xmld As XmlDocument
            Dim m_node As XmlNode
            resultMsgType = ""
            pmsId = ""
            memberNr = ""
 
            m_xmld = New XmlDocument()
            m_xmld.Load(inReader)
            m_node = m_xmld.SelectSingleNode("//RESULT/ResultIds/ResultId")
 
            resultMsgType = m_node.Attributes.GetNamedItem("resultMsgType").Value
            pmsId = m_node.ChildNodes.Item("pmsId").InnerText
            memberNr = m_node.ChildNodes.Item("memberNr").InnerText
 
        Catch ex As Exception
            Dim ER As New GXIErrors
            ER.NewRecord()
            ER.ErrorText = ex.Message
            ER.ErrorLocation = "ReadXML"
            ER.Save()
        End Try
    End Sub
End Class
