Now you’ve seen how to create a DOM document in memory, how to read one from disk, and how to manipulate one. You’ve looked at some different ways to manipulate a document once it’s in memory, and you’ve used two XmlDocument instances simultaneously to manage an inventory system.

I also introduced XPath in this chapter. There’s a lot more to say on that subject, so in Chapter 6 you’ll learn about the System.Xml.XPath assembly.
