For Each myNode As XmlNode In xd.DocumentElement.ChildNodes
' MsgBox(myNode.LocalName.ToString)
If myNode.Attributes.ItemOf("Cid", uri).Value.ToString = intid Then

' myNode.ParentNode.ParentNode.RemoveChild((myNode.ParentNode))

myNode.ParentNode.RemoveChild(myNode)

End If
xd.Save(mXmlFilePath)
Next
i have changed this code now its deleting first node every time

Please, refer these:
Removing Nodes, Content, and Values from an XML Document [^]
Removing Elements, Attributes, and Nodes from an XML Tree[^]
Modifying Nodes, Content, and Values in an XML Document[^]

[EDIT #1]
Change below code to your needs...

VB

Dim xmlDoc As Xml.XmlDocument = Nothing, xmlRoot As Xml.XmlNode = Nothing
       Dim xmlNode As Xml.XmlNode = Nothing, xmlChild As Xml.XmlNode = Nothing

       Try
           xmlDoc = New Xml.XmlDocument()
           xmlDoc.Load("E:\MyXML.xml")
           xmlRoot = xmlDoc.DocumentElement()
           xmlNode = xmlRoot.ChildNodes(1)
           For Each xmlChild In xmlNode
               MsgBox(xmlChild.Name & vbCr & xmlChild.InnerText)
           Next

       Catch ex As Exception
           MsgBox(ex.Message, MsgBoxStyle.Exclamation, "Error")

       Finally
           xmlRoot = Nothing
           xmlNode = Nothing
           xmlDoc = Nothing
       End Try
