Imports System.Xml
Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim xmlFile As XmlReader
xmlFile = XmlReader.Create("Product.xml", New XmlReaderSettings())
Dim ProductIDList As XmlNodeList =
ProductXml.SelectNodes("/url/loc")
For Each ProductNode As XmlNode In ProductIDList
LoadProduct(ProductNode.InnerText)
Next

End Sub
