I have an XML document that contains images that I use to display on the page.  I need to be able to update the images in the XML document.  I have a control panel on my page that has the list of images that should be in the XML.  How do I delete the images and repopulate the XML document?  The code below allows me to get the images so now I just need to know how to delete them and replace them with the new list.
Dim xmlDoc As New XmlDocument
        xmlDoc.Load(Server.MapPath("images.xml"))

        Dim nodeList As XmlNodeList
        Dim root As XmlNode = xmlDoc.DocumentElement
        Dim img As XmlNode
        nodeList = root.SelectNodes("descendant::image")

something like so:
Dim xmlDoc As New XmlDocument()
xmlDoc.Load(Server.MapPath("images.xml"))
Dim nodes As XmlNodeList = xmlDoc.SelectNodes("//image")
For Each node As XmlNode In nodes
	node.ParentNode.RemoveChild(node)
Next

you just need to add the following below to your code to delete them:
For Each node As XmlNode In nodeList
	node.ParentNode.RemoveChild(node)
Next

To add just do something like so:

Dim elem As XmlElement = xmlDoc.CreateElement("image")
Dim text As XmlText = xmlDoc.CreateTextNode("Image Name")
xmlDoc.DocumentElement.AppendChild(elem)
xmlDoc.DocumentElement.LastChild.AppendChild(text)
