What do you mean edit/delete?

All you need is to traverse the XML nodes and make changes. Is that you are trying to ask?

Here is a simple code to delete a node :

C#

XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(@"C:\Test.xml");
            XmlNode elem = xmlDoc.SelectSingleNode("/slideshow/image[position()=1]");
            XmlNode root = xmlDoc.DocumentElement;
            root.RemoveChild(elem);
            xmlDoc.Save(@"C:\Test.xml");

The SelectSingleNode uses an Xpath expression with position set to 1 as you want to delete the first element.

To edit:

Since you only have attributes, you can edit in this way :

C#

elem.Attributes["imagePath"].Value = "ddd";

And to insert a new element :

C#

XmlElement newElement = xmlDoc.CreateElement("Image");
            XmlAttribute attr = xmlDoc.CreateAttribute("path");
            attr.Value = "Add you path here";
            newElement.Attributes.Append(attr);

            root.InsertAfter(newElement, root.LastChild);
