This chapter has shown you how you can make use of your existing XML skills in C#. You saw how to manipulate the nodes of an XML document using the DOM class XmlDocument, and you saw how to query XML documents using XPath statements. Finally, you saw how to transform XML documents using XSL transformations.
This chapter didn't go into much detail on the individual standards such as XSL and XPath. If you need to know more about those, many references are readily available.
Now that you have completed this chapter, you should feel comfortable working with XML in any of its forms whether you're working on an ASP.NET application or a Windows Forms application.
