XML: Introduction

Course Description:

XML is a meta-language for describing markup languages. XML offers the capability to define tags and the structural relationships between them and omits the need for predefined tags. This eliminates the unnecessary restrictions faced when coding in HTML which explains XML's fast growing popularity.

This practical hands-on course is designed to give HTML coders a comprehensive introduction to XML (plus DTD, Namespaces and RSS) and the emerging technologies of Xlink, Xpointer and Xinclude.

This two day intensive course can also be taken as a three day course on an individual tuition or private company basis for those inexperienced with hand coding HTML and CSS.
