Both the XMlDocument object and the Dataset object can load xml files and if you pass a url instead of a local path it will still retrieve the file.
VB Code:
'using an XMLDocument
Dim xDoc As New Xml.XmlDocument()
xDoc.Load("http://mage.edneeis.com/_private/traffic.xml")
'get a node
Dim xNode As Xml.XmlNode = xDoc.SelectSingleNode("Traffic/AutoLogins")
'using a Dataset
Dim ds As New DataSet()
ds.ReadXml("http://mage.edneeis.com/_private/traffic.xml")
'show results
MsgBox(String.Format("Total Hits= {0} : Auto Logins= {1}", ds.Tables(0).Rows(0)("TotalHits").ToString, xNode.InnerText))
