Creating XML Taxonomies
(Page 1 of 4 )
Welcome to the third part of a five-part series that introduces you to extensible markup language, also known as XML. The first two parts of this series served as an introduction and an overview, to help you get to know some of the things you can do with it. In this article we will roll up our sleeves and actually start learning how to build things with the language, by getting a better understanding of how its structures work. That's right, you will actually learn how to handle data.
Creating XML Taxonomies
In this article I will teach you how to take your data and break it down into groups, creating a taxonomy of categories and subcategories. For our examples, we will assume that you are starting an XML document that will provide the structure for a warehouse of data for a music store that has both a physical location and a web presence.
In our last article we talked about the linguistics of XML, learning the definitions of such words and phrases as Document Type Definitions, XML Schemas, well formed documents, valid documents, elements, attributes, and much more. We discussed how to tell what type of information you presently had, such as spreadsheet and database files. We ended the article talking about some of the off-branches of XML you might encounter, such as SOAP, XSLIT, and SVG.
To start this article we are going to talk about our music store and all of the different fields we might need. That's one of the best parts about XML; it's so flexible that it's easy to put your needs first.
