Question

我无法从以下文档中获取XML值。

我已多次尝试过，但我无法让它发挥作用。

Dim tr As IO.TextReader = New IO.StreamReader("E:\response.xml")

'Do While xmlFile.Read()
Dim doc As XmlDocument = New XmlDocument()
doc.LoadXml(tr.ReadToEnd)
For Each eventNode As XmlNode In doc.SelectNodes("ResponseRecord")
    If xmlFile.NodeType = XmlNodeType.Element AndAlso xmlFile.Name = "AddressLine1" Then
        Console.WriteLine(xmlFile.GetAttribute(0))
        Console.WriteLine(xmlFile.a("AddressLine1").ToString)
    End If
Next

XML DOC：

您需要使用XmlNamespaceManager，因为您的XML文档确实具有名称空间：

Dim doc As XmlDocument = New XmlDocument()
Dim nsmgr As XmlNamespaceManager = New XmlNamespaceManager(doc.NameTable)
nsmgr.AddNamespace("ns", "http://schemas.xxxxxxxx.org/2004/07/WcfServiceMD.mdContactVerify")

doc.Load("E:\response.xml")
For Each record As XmlElement In doc.SelectNodes("/ns:Response/ns:Records/ns:ResponseRecord", nsmgr)
    Console.WriteLine(record.SelectSingleNode("ns:AddressLine1", nsmgr).InnerText)
Next
