Chapter 2: Building an XML Document Editor

Highlights

Extensible markup Language (XML) has been a successful rising star in the computing industry. Developed by the World Wide Web Consortium (W3C) in 1996, XML is now a widely accepted standard for data exchange and extensible data structure.

As XML becomes more popular, a need arises to write and edit XML documents. The project in this chapter is an XML document editor that you can use to edit multiple XML documents, validate each document, build a tree based on elements in each document, and so on. This XML editor is a Multiple Document Interface (MDI) application, so you can open and work with multiple documents at the same time.

Note

The objectives of this project are twofold: demonstrating how to write an MDI application and showing how to program XML in the .NET Framework.
