Using XML with Legacy Business Applications
by Michael C. Rawlins
Daniel Appelquist, Senior Architect at Vodafone and author of XML and SQL: Developing Web Applications (Addison-Wesley, 2002).
“”Unlike other books that simply cover XML standards and specifications, this book shows you how to actually use XML to solve real-world problems. Developers trying to see through all the hype and discover the real utility of XML will finally appreciate having a book that uses industrial-strength examples to make it all crystal clear.”
Stephen Vinoski, IONASimple guidance for bridging the gap between XML and legacy applications
Businesses running legacy applications that do not support XML can face a tough choice: Either keep their legacy applications or switch to newer, XML-enhanced applications. XML presents both challenges and opportunities for organizations as they struggle with their data.
Does this dilemma sound familiar? What if you could enable a legacy application to support XML? You can. In “Using XML with Legacy Business Applications, e-commerce expert Michael C. Rawlins outlines usable techniques for solving day-to-day XML-related data exchange problems. Using an easy-to-understand cookbook approach, Rawlins shows you how to build XML support into legacy business applications using Java and C++. The techniques are illustrated by building converters for legacy formats. Converting CSV files, flat files, and X12 EDI to and from XML will neverbe easier!
Inside you’ll find: A concise tutorial for learning to read W3C XML schemasAn introduction to using XSLT to transform between different XML formatsSimple, pragmatic advice on transporting XML documents securely over the internet
For developers working with either MSXML with Visual C++ or Java and Xerces: See Chapter 3 for a step-by-step guide to creating XML documents from existing business applicationsSee Chapter 2 for a step-by-step guide on reading XML documents into existing business applicationsSee Chapter 5 for code examples and tips for validating XML documents against schemasSee Chapter 12 for general tips on building commerce support into an application
For end users who need a simple and robust conversion utility: See Chapter 7 for converting CSV files to and from XMLSee Chapter 8 for converting flat files to and from XMLSee Chapter 9 for converting X12 EDI to and from XMLSee Chapter 11 for tips on how to use these techniques together for complex format conversions
The resource-filled companion Web site (http: //www.rawlinsecconsulting.com/booksupplement) includes executable versions of the utilities described in the book, full source code in C++ and Java, XSLT stylesheets, bug fixes, sample input and output files, and more.
Voltage-Sourced Converters in Power Systems
by Amirnaser Yazdani, Reza Iravani
Presents Fundamentals of Modeling, Analysis, and Control ofElectric Power Converters for Power System Applications
Electronic (static) power conversion has gained widespreadacceptance in power systems applications; electronic powerconverters are increasingly employed for power conversion andconditioning, compensation, and active filtering. This bookpresents the fundamentals for analysis and control of a specificclass of high-power electronic converters—the three-phasevoltage-sourced converter (VSC). Voltage-Sourced Converters inPower Systems provides a necessary and unprecedented link betweenthe principles of operation and the applications of voltage-sourcedconverters. The book:
- Describes various functions that the VSC can perform inelectric power systems
- Covers a wide range of applications of the VSC in electricpower systems—including wind power conversion systems
- Adopts a systematic approach to the modeling and control designproblems
- Illustrates the control design procedures and expectedperformance based on a comprehensive set of examples and digitalcomputer time-domain simulation studies
This comprehensive text presents effective techniques formathematical modeling and control design, and helps readersunderstand the procedures and analysis steps. Detailed simulationcase studies are included to highlight the salient points andverify the designs.
Voltage-Sourced Converters in Power Systems is an idealreference for senior undergraduate and graduate students in powerengineering programs, practicing engineers who deal with gridintegration and operation of distributed energy resource units,design engineers, and researchers in the area of electric powergeneration, transmission, distribution, and utilization.

Special Edition Using XML, Second Edition gives developers a formal introduction to XML technology, starting with in-depth coverage of basic syntax and fundamental “pieces” of XML, including DTDs, Schemas, and Namespaces. The authors then cover various applications of XML, including transforming and displaying XML documents using CSS and XSL, locating data within XML documents using Xpath, Xlink and Xpointer, programming XML with SAX or DOM, including XML in Java or .NET applications, XML Scripting with Perl, XHTML and WML for presentation on traditional and hand-held Web browsers, and querying data or documents with Xquery. The final chapters cover technologies related to XML such as SVG, SMIL, and RDF, focusing on the practical features developers can put to use today.
