Question

I am currently trying to read in an XML node from a filepath which I pass to my method.

Public Function ReadXMLForIsite(xmlFileName As String)
    Dim IsitePath As String
    Dim doc As New XPathDocument(xmlFileName)
    Dim nav As XPathNavigator
    Dim iter As XPathNodeIterator

    nav = doc.CreateNavigator
    iter = nav.Select("GovTalkMessage/Header") 'Node name
    'Loop through the records in that node
    While iter.MoveNext
        Dim lstNav As XPathNavigator
        'Get the data we need from the node
        Dim iterNews As XPathNodeIterator
        lstNav = iter.Current
        iterNews = lstNav.SelectDescendants(XPathNodeType.Element, False)
        'Loop through the child nodes
        While iterNews.MoveNext
            Debug.WriteLine(iterNews.Current.Name & ": " & iterNews.Current.Value)
        End While
    End While

    Return IsitePath
End Function

Every time i run this method (even with different node names) the variable ‘iter’ states that ‘debugger display proxy is a type and cannot be used as an expression’. This occurs just before the while statement, therefore does not go in. Any help would be much appreciated. Thanks!

Try to load your Xml into an XDocument.

Dim xdoc As XDocument = XDocument.Load("X:\Jacob.Freeman\RTI\TestXML\0001R.xml")
Dim headerNode = xdoc.Descendants.First(Function(x) x.Name.LocalName = "Header")
For Each desc In headerNode.Descendants()
  Console.WriteLine(desc.Name.LocalName + ":" + desc.Value)
Next
Console.ReadLine()
