XML Training Overview
This course provides a complete introduction to XML and the Java XML APIs. The course is a balanced mixture of theory and practical labs, designed to take students from the basic fundamentals of XML, right through to mastery of the standard Java XML APIs. The students are walked through the different standards in a structured manner, to enable them to master the concepts and ideas, which are reinforced in the lab exercises.
The course starts with the fundamentals of XML including document structure, and XML Schema. It then moves on to the basic relationship between Java and XML, including generating XML from Java and the mapping between Java and XML objects. Finally, students are taken through a detailed and hands-on examination of the two main JAXP APIs – SAX 2.0 and DOM 2.0. The course concludes with a look at some Java and XML related topics.
Hands-on:
50% hands-on, 50% lecture
Supported Platforms:
Java 1.4+
