Summary

This lesson took a dramatic turn toward the practical and the entertaining by showing you how XML is used in an extremely popular real-world application. More specifically, you learned how an iTunes music library is coded as an XML document that can be manipulated without too much difficulty. You worked through the specific XML format used by iTunes as well how to create an XSLT stylesheet that drills into that format and extracts information about individual tracks. This hour even showed you how to construct hyperlinks to the iTunes music store so that you can provide links between your music library and iTunes for people to buy the songs listed in your library. All of this learning culminated in a complete example that allows you to make your iTunes music library available on the Web for other people to view and use as a basis for shopping for iTunes music.
