Introduction to XML Training Class Summary

The Extensible Markup Language (XML) defines a way of marking up text to describe the structure of data. XML allows you to create your own markup language: you define the tags that give meaning to your data. The World-Wide Web Consortium (W3C) creates and maintains the definition of XML, making it a standard for creating markup languages. Industries and organizations use XML to write rules defining their own markup languages.

In this course, students will learn how to create well-formed XML documents. By adding a third day to the course, we've enhanced Introduction to XML by extending our coverage of XML Schema and XSLT. A new chapter covering XML Schema in conjunction with Namespaces supplements a trio of existing chapters on XML, Namespaces, and XML Schema. The additional three chapters on XSLT give students more than just a jump start on XSLT, but rather full, in-depth coverage of this complex topic.

Audience: Application developers, web developers and administrators, and XML authors.

Prerequisites: HTML. Familiarity with web and data processing concepts. Programming experience is helpful, but not necessary.

Class Length: 3 days

Introduction to XML Training Class Objectives
  • Explain what XML is, and how it is used in application and document development.
  • Write well-formed documents that conform to XML's basic rules of syntax.
  • Validate XML documents with both DTDs and XML Schemas.
  • Identify the key differences between DTDs and XML Schemas.
  • Use XML Namespaces to distinguish between XML tags.
  • Transform an XML document into an HTML document using XSLT.
  • Use XPath to navigate a document tree.
  • Explain how programs can use DOM and SAX to parse XML documents.
