"This volume offers relentlessly pragmatic solutions to help your business applications get the most out of XML, with a breezy style that makes the going easy. Mike has lived this stuff; he has a strong command of the solutions and the philosophy that underlies them.">-Eve Maler, XML Standards Architect, Sun Microsystems

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 never be easier!

Inside you'll find:

• A concise tutorial for learning to read W3C XML schemas

• An introduction to using XSLT to transform between different XML formats

• Simple, pragmatic advice on transporting XML documents securely over the Internet
