Welcome to the DevGuru XSLT Quick Reference guide. This is a comprehensive 101-page reference source for all of the elements and functions that compose the eXtensible Stylesheet Language Transformation (XSLT) language version 1.0. This Quick Reference features real working code examples which were tested using the Microsoft XML parser version 3.0.
XML is one of the most important of all recent innovations to hit the web. The XML technology provides a means of storing data in a structured manner. If you are not familiar with XML and would like an introduction, the Guru strongly recommends that you read the following two-part tutorial:
A Beginners Guide to Creating and Displaying Your First XML Document.
The question (and programming challenge!) is how to access and display the information contained in an XML file. After all, data is useless unless you can use it. This is where XSLT comes into the picture.
A comparison can be made between the relationship of CSS and HTML and the relationship of XSLT and XML. Indeed, XSLT is usually referred to as the stylesheet language of XML, however XML and XSLT are far more sophisticated technologies than HTML and CSS.
XSLT is a high-level declarative language. It is also a transforming and formatting language, and that describes exactly how XSLT behaves:
