XML, the EXtensible Markup Language, is the web standard for generic representation of structured data. Perhaps it hasn't yet found its way into your company's ABAP application development, but there is a fair chance that it will. So how can you bridge the gap between the ABAP and XML worlds? The SAP Web Application Server offers an implementation of the XSLT (EXtensible Stylesheet Language Transformations) standard to establish mappings between XML documents and ABAP data structures. This article teaches you how to create and call XSLT programs, and how your programs can use XSLT to interface with XML from ABAP.
