XML Training : Using XML in Java Applications

This course will, through lecture and extensive hands-on workshops, teach you to manipulate XML generally in a data-processing environment, with emphasis on Java as the programming vehicle. Specifically, you will learn to write Java applications that can:

Read and parse XML documents
Generate XML documents
Integrate XML with traditional structured data
Perform queries on XML

Note: Although many of the skills learned in this course may apply to applications that present XML on the Web, the clear emphasis here is on handling XML as data rather than on presentation.

XML Training Prerequisites

Introduction to XML, as well as a solid knowledge of Java

XML Training Course duration

2 Days

XML Training Learning Objectives

This course will teach you how to access and process XML documents from a Java application. Specifically, you will learn:

How to use Java implementations of the two major parser APIs -- SAX and DOM -- to parse XML documents.
How to create Java classes to convert a document into application objects and vice-versa.
How to load XML-parsing Java code dynamically with the document.
How an XML-capable relational database can integrate XML with traditional structured data.
