การค้นหาข้อมูลจากXML ขอคำแนะนำหน่อยครับ เพื่อจะนำมาศึกษา

Dim dsProducts As New DataSet()
dsProducts.ReadXml("productlist.xml")

Dim dvProducts As New DataView(dsProducts.Tables("Products"))
dvProducts.Sort = "SKU"

Dim rowIndex As Integer = dvProducts.Find("1")
Dim Price As String, Description As String

If rowIndex = -1 Then
	' The SKU was not found in our data
	Console.WriteLine("Product Not found")
Else
	Price = dvProducts(rowIndex)("Price").ToString()
	Console.WriteLine("Price: " & Price)
	' Price: 100.00

	Description = dvProducts(rowIndex)("Description").ToString()
		' Description: Widget #1
	Console.WriteLine("Description: " & Description)
End If
