CHAPTER 22 ■ PROJECT 3: XML FOR ALL OCCASIONS 437
Further Exploration
Now you’ve got the basic program. What can you do with it? Here are some suggestions:
• Create a new ContentHandler for creating a table of contents or a menu (with links) for
the Web site.
• Add navigational aids to the Web pages that tell the user where (in which directory) he or
she is.
• Create a subclass of WebsiteConstructor that overrides writeHeader and writeFooter to
provide customized design.
• Create another ContentHandler that constructs a single Web page from the XML file.
• Create a ContentHandler that summarizes your Web site somehow, for example in RSS
(see Chapter 15).
• Check out other tools for transforming XML, especially XSLT (see http://www.w3.org/
TR/xslt and http://www.4suite.org).
• Create one or more PDF documents based on the XML file, using a tool such as
ReportLab’s Platypus (http://reportlab.org).
• Make it possible to edit the XML file through a Web interface (see Chapter 25).
What Now?
After this foray into the world of XML parsing, let’s do some more network programming. In the
next chapter, you create a program that can gather news items from various network sources
(such as Web pages and Usenet groups) and generate custom news reports for you.
