"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
