A Gentle Introduction to
Interactive XML tutorials.
These tutorials introduce a variety of XML topics including, SVG,
DTD, Schema, XSLT, DOM and SAX.
Each topic includes a number of problems that the student must complete.
For all of the problems the student has access to online parsers that
process the students answers and give immediate feedback.
- SVG - Scalable Vector Graphics
- SVG is an example of an XML application.
Using SVG we can create images made up of lines, shapes and text.
- DTD - Document Type Definition
A DTD describes an XML application. An XML documents may be
validated against a DTD. The DTD specifies the elements that
may be included, how they may be nested and what attributes
each element may have.
- XSLT Extensible Style Sheet Transformations
An xsl sheet describes the transformation of an XML document.
The xsl transformation involves matching nodes against templates.
The xsl transfomation may use XPath expressions.
- DOM at progzoo
- DOM - Document Object Model
The Document Object Model includes a set of classes that have been
implemented in a variety of languages. In these examples we use
Java to process XML documents using DOM.
- SAX - Simple API for XML
The SAX interface allows us to process XML documents in Java.
Although this interface is harder to use (than DOM) it is more
efficient and allows us to process large documents without the
overheads that DOM introduces.
- XML Schema
A schema may be used to validate an xml document. Schema perform
more or less the same function as a DTD - they do it better but
are considerably more complex.
All of the tools used are freely available.
The web interface is convenient for beginners however more ambitious
students should be able to install the tools and run the examples
from their own machines.
