Processing XML documents with Oracle JDeveloper 11g

Overview of this book

XML is an open standard for creating markup languages and exchanging structured documents and data over the Internet. JDeveloper 11g presents an effective, quick, and easy-to-use means of processing XML documents. Inspired by the author's previous XML articles for the Oracle community, this expanded hands-on tutorial guides newcomers and intermediate users through JDeveloper 11g and XML document development. It offers up-to-date information on working with the latest version of JDeveloper, and brand new information on JAXB 2.0 support in JDeveloper 11g. Filled with illustrations, explanatory tables, and comprehensive instructions, this book walks the reader through the wide assortment of JDeveloper's capabilities. Oracle's JDeveloper 11g is an Integrated Development Environment that provides a visual and declarative approach to application development. Over the course of 14 chapters, readers will get hands-on with JDeveloper as the comprehensive and self-contained tutorials provide clear instruction on the key XML tasks that JDeveloper can accomplish. Filled with practical information and illustrated examples, this book shows the reader how to create, parse, and store XML documents quickly, as well as providing step-by-step instructions on how to construct an XML schema and use the schema to validate an XML document. Oracle's XML Developer Kit (XDK) offers a set of components, tools, and utilities for developing XML-based applications, and developers will find the detailed XDK coverage invaluable. Later chapters are given over to using XPath, transforming XML with XSLT, and using the JSTL XML Tag Library. Moving through the book, a chapter on the JAXB 2.0 API shows you how to bind, marshal and unmarshal XML documents, before we finally delve into comparing XML documents, and converting them into PDF and Excel formats. In all, this book will enable the reader to gain a good and wide-ranging understanding of what JDeveloper has to offer for XML processing.

Preface

Overview of the JSTL XML tag library


In this section we shall discuss the XML tags in the JSTL XML tag library. We will use some of the tags in a subsequent section in a JSTL XML example application. The JSTL XML tag library provides various tags for parsing an XML document, selecting nodes in an XML document with XPath, iterating over document nodes, and transforming an XML document. The JSTL XML tag library URI is http://java.sun.com/jsp/jstl/xml. The syntax for including the JSTL XML tag library in a JSP page is the following taglib directive:

<%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml" %>

The different tags in the JSTL XML tag library are discussed in the table that follows. All of the attributes are of type java.lang.String, except the begin, end, and step attributes in the forEach tag, which are of type int, and attributes are not required unless specified to be required.
