Introduction to XML
EXtensible Markup Language (XML) is a software and hardware independent tool for storing and transporting data.
That say’s it all! XML are flat files designed to carry data - with focus on what data is.
XML history begins with the development of Standardized Generalized Markup Language (SGML) in the 1970’s by Charles Goldfarb along with Ed Mosher and Ray Lorie while working at IBM (Anderson, 2004).
