Using XML In Java Training Course

Duration: 2 days
Course code: SS-JAV-031

Audience
  • Application developers
  • Any Java Application Developers who want to incorporate XML into Java applications
Prerequisites

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

Description

Using XML in Java Training 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.

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 major parser APIs - SAX, DOM, JDOM, etc. - to parse XML documents.
  • How to create Java classes to convert a document into application objects and vice-versa.
  • How to load vendor specific XML-parsers dynamically with the document.
  • How to transform XML with XSL using XSLT engines.
