XML is at the heart of a number of developments that are likely to become basic technology standards, such as Web services. In turn, the ability to move data between XML documents and your ABAP data structures is becoming a key business requirement.

It outlines the fundamental concepts of the language, and provides a detailed tour of its key constructs.
