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.

Chapter 14. Oracle XML Publisher

In Chapter 11 we generated a PDF report using the Apache FOP API, and in Chapter 12 we generated an Excel spreadsheet using the Apache POI API. Oracle also provides a reporting tool to generate reports. Oracle provides the Oracle XML Publisher to generate AWR, Excel spreadsheet, HTML, PDF, RTF, and UIX reports. Oracle XML Publisher is available as a GUI tool as well as a set of core API components. The Oracle XML Publisher has many advantages over the Apache FOP/Apache POI APIs, some of which are discussed as follows:

  • Reports may be generated from multiple input XML files

  • XML documents are not required to be parsed using the JAXP/XPath API

  • PDF documents may be merged

  • XML Publisher supports other formats such as HTML and RTF in addition to PDF and Excel spreadsheet

The following core APIs may be integrated with Oracle JDeveloper 11g to generate PDF, Excel, HTML, or RTF reports:

  • PDF Form Processing Engine API: This merges a PDF template with XML data to generate...
