Private Shared xmlDoc As XmlDocument          
 xmlDoc = New XmlDocument
            xmlDoc.Load(FilePath)

 For Each EnumDll In xmlDoc.ChildNodes.Item(1).ChildNodes 'root node

     For Each xmlNodeitem As XmlNode In EnumDll.ChildNodes 'child Nodes
          Label1.Text = CType(xmlNodeitem.ChildNodes.Item(2).InnerText, String)
     Next'child node

Next


try above code

How would I reference a dataset?

I have the data in a dataset which I've been parsing out with hard coded node lists...which I absolutely do not want to do...

Please see the code AND the actual XML below


------Dataset Code That has been getting "node list" for different repeaters-------
blah...blah...blah...
Session("response").WriteXml(xmlTextWriter, XmlWriteMode.IgnoreSchema)
 
        ' Write the Xml out to a string   
        Dim contentAsXmlString As String = stringWriter.ToString()
 
        ' load the string of Xml into the document   
        xmlDocument.LoadXml(contentAsXmlString)
 
        ' parse out the session token 
        Dim _response As XmlNodeList = xmlDocument.SelectNodes("//responseEnvelope/responseHeader/statusData")
        Dim _response2 As XmlNodeList = xmlDocument.SelectNodes("//responseEnvelope/ReservationResponse/ReservationToken")
 
        Dim _response3 As XmlNodeList = xmlDocument.SelectNodes("//responseEnvelope/ReservationResponse")
Dim _response2 As XmlNodeList = xmlDocument.SelectNodes("//responseEnvelope/ReservationResponse/ReservationToken")
 
        Dim _response3 As XmlNodeList = xmlDocument.SelectNodes("//responseEnvelope/ReservationResponse")
 
 
 
        hdr.DataSource = _response
        hdr.DataBind()
 
        hdr2.DataSource = _response2
        hdr2.DataBind()
 
        hdr3.DataSource = _response3
        hdr3.DataBind()
 
 
---ACTUAL DATA------
<?xml version="1.0"?>
<responseEnvelope>
    <responseHeader>
        <statusData>
            <completionCode>0</completionCode>
            <completionMessage>Request Completed Successfully.</completionMessage>
        </statusData>
    </responseHeader>
    <ReservationResponse>
        <ReservationToken>
            <inventoryType>1</inventoryType>
            <referenceNumber>73510000113587001</referenceNumber>
            <unitNumber>1856</unitNumber>
        </ReservationToken>
        <status>C</status>
    </ReservationResponse>
</responseEnvelope>

So first you are writing data from dataset to xml and then you want to use that xml to populate labels or repeater? Why not use the dataset directly?

lblTest.Text = dSet.Tables(0).Rows(0).item("Name")

The data is coming back from a reote form post as XML
I can't write these to files...
I'm passing the data to a processing form as a Session("response") and then placing that as a dataset

I'll try what you placed there.

If you look at my XML Data above...you'll see that your reply is looking at the top tier...
How do I point it to other "levels"

Column 'referenceNumber' does not belong to table responseHeader.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentException: Column 'referenceNumber' does not belong to table responseHeader.

Source Error:
Line 222:        Dim dSet As New DataSet()
Line 223:        dSet = Session("response")

Code Cruiser put me close to what I needed....channa_m: was helpful as well.

Final solution to access the child information was...
lblData.Text = dSet.Tables("ReservationToken").Rows(0).Item("referenceNumber").ToString
