XML Programming Using Java

XML Programming Using Java

nTier’s XML Programming Using Java course builds skills in Java’s XML processing APIs â€?chiefly parsing using SAX and DOM and transformations using XSLT, all using the Java API for XML Processing, or JAXP. It also covers the newer Java API for XML Binding, or JAXB, which standardizes serialization according to XML Schema.

The course is intended for students with a working knowledge of XML �and possibly DTDs or XML Schema �who want to build XML applications or components using the Java language. Everything in the course adheres to W3C and Java standards for completely portable code.

The first module introduces the JAXP and the two main Java APIs for parsing XML documents: SAX and the DOM. Students learn the basic JAXP architecture and how to create parsers that expose SAX or DOM APIs, and how to configure parsers according to the SAX features and properties specification. SAX parsing is covered, working from simple SAX event handling through patterns for understanding document content from event sequences, to error handling and document validation. Students then learn how to read document information using the DOM’s tree model and API, and move on to using the DOM to modify and to create new documents and information nodes. The final two chapters of this module cover the DOM2 Traversal and Events modules and the JAXB, with a focus on XML serialization and persistence.

The second module introduces students to the XPath and XSLT specifications, and how to use JAXP as an interface to XML transformations. Students learn the basic JAXP Transformer architecture, develop fluency in the exacting but powerful XPath syntax, and then build a number of XSLT transformations. Study of XSLT is arranged first to develop control over output production, including a solid understanding of the sometimes mysterious built-in template rules, template matching, priority and modes, and control of whitespace production. Then students turn towards the source document and learn to extract single values, to make shallow and deep copies of source elements, to use variables, and to use flow-control constructs to effect conditional processing and loops. In the module’s final case study, students build a servlet-based Web application that uses JAXP and XSLT to produce dynamic content based on an XML data source.

The course software also includes an optional overlay of workspace and project files to support use of the Eclipse IDE in the classroom.

This course focuses on XML application development. This class provides a thorough explanation of the Extensible Stylesheet Language for Transformations (XSLT) and the two API’s for XML including the Document Object Model (DOM) and the Simple API for XML (SAX).

Audience: This course is designed for Application Developers who have a working knowledge of Java and require in-depth knowledge of how to create and process XML documents within their XML applications.

Topics:
Overview
XML Transformations (XSLT)
Producer Applications using JDBC
The Simple API for XML (SAX)
The Document Object Model
Processing XML documents using the DOM
Prerequisites: The student should have attended ProTech’s Introduction to Java and Introduction to XML courses or have equivalent experience.
