XML Programming Using Java

 

XML Programming Using Java – 4 Days

Course Description

This XML Programming Using Java four-day training course builds skills in Java’s XML processing APIs. 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 course comprises three modules, which treat XML parsing, XML transformations, and XML binding. The first module introduces the Java API for XML Processing (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 gives way to reading and writing document information using the DOM tree model and API.

The second module introduces students to the XPath and XSLT specifications, and how to use JAXP as an interface to XML addressing and transformations. Students learn the JAXP’s innovative system of Transformers, Sources, and Results; develop fluency in the exacting but powerful XPath syntax; and then build a number of XSLT transformations.

The third module introduces the newer and more powerful Java API for XML Binding, or JAXB, in its current incarnation, which is version 2.1. JAXB is now emerging as the tool of choice for most XML processing tasks where an XML Schema is available or easy to derive: based on that schema, JAXB-generated types can make it quite easy to read, manipulate, and write XML information models.

What You Will Learn

  • Understand the use of SAX and DOM APIs for XML parsing.
  • Understand the need for JAXP as an additional layer to the standard contract between applications and parsers.
  • Parse element and attribute content, processing instructions, and other document information using SAX.
  • Parse documents using the DOM.
  • Modify, create and delete information in an XML document using the DOM.
  • Write simple and complex queries into XML document content using XPath.
  • Use XSLT for XML-to-XML, XML-to-HTML, or XML-to-text transformations.
  • Build standalone and web applications that build on XSLT transformation logic.
  • Use JAXB to generate persistent Java object models based on XML Schema.
  • Implement XML persistence using the JAXB.

Prerequisites

  • Experience in Java Programming, including object-oriented Java and the Java streams model, is essential.  Java Programming, is excellent preparation.
  • Basic understanding of XML is required.  Introduction to XML, is recommended.
  • XML Schema is used peripherally in the course, and knowledge of this technology will be helpful, but is not required.
