Consider using XMLTextReader. This example just loads the entire XML into a string, but obviously you could write it to a file instead:

    Dim strUrl As String = "http://xyz.com"
    Dim reader As XmlTextReader = New XmlTextReader(strUrl)
    Dim output as String

    Do While (reader.Read())
        Select Case reader.NodeType
            Case XmlNodeType.Element 

                Output = Output + "<" + reader.Name

                If reader.HasAttributes Then 
                    While reader.MoveToNextAttribute()
                        Output = Output + " {0}='{1}'", reader.Name, reader.Value)
                    End While
                End If
                Output = Output + ">"
            Case XmlNodeType.Text
                Output = Output + reader.Value
            Case XmlNodeType.EndElement
                Output = Output + "</" + reader.Name + ">"
        End Select
    Loop

Why not just use the WebClient class and its DownloadFile method?? Seems a lot easier....

This is in C#, but you should have no trouble converting that to VB.NET:

WebClient wc = new WebClient();
wc.DownloadFile("http://xyz", @"C:\getxml.xml");

and you're done!

What if the service is sending the request to our URL? How do I adjust this to read the http stream they send? Having such a hard time... (Should I do a separate thread? Sorry.)
