Here is what I have so far,and tried different ways but always ending up erasing it.:(

 Sub GetData()


        Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create("target url")
        request.Credentials = New System.Net.NetworkCredential("user", "pass")
        Dim response As System.Net.HttpWebResponse = request.GetResponse()
 开发者_StackOverflow       If response.StatusCode = System.Net.HttpStatusCode.OK Then

          Dim stream As Stream = response.GetResponseStream()
            ' Create a reader for the stream object
            Dim reader As New StreamReader(stream)
            ' Read from the stream object using the reader, put the contents in a string
            Dim contents As String = reader.ReadToEnd()
            ' Create a new, empty XML document
            Dim HttpResult As New XmlDocument
            Dim UserInfo As XmlNodeList
            Dim Discription As XmlNode
            HttpResult = New XmlDocument
            HttpResult.LoadXml(contents)


            'Create the XML Document
            HttpResult = New XmlDocument()
            Dim _XPath As String =
            UserInfo = HttpResult.SelectNodes("")



            'Get the Gender Attribute Value
            Dim DetailsAttribute = Discription.Attributes.GetNamedItem("").Value
     endif

    End Sub

Start with this...

Dim MyDoc as New System.Xml.XmlDocument
MyDoc.Load("c:\path\to\your\xml\file")

Dim MyNode as System.Xml.XmlNode = MyDoc.SelectSingleNode("//system/colors/type")

Dim RedAttribute as String = MyNode.Attributes("red").Value
Dim GreenAttribute as String = MyNode.Attributes("green").Value
Dim YellowAttribute as String = MyNode.Attributes("yellow").Value
Dim BlackAttribute as String = MyNode.Attributes("black").Value

I think that should get you where you want to go.
