eXtensible Markup Language

The eXtensible Markup Language (XML) is a document creation language. It was developed by the World Wide Web Consortium to replace Hyper Text Markup Language (HTML) which is used to create web pages.

It is a widely-implemented standard for data exchange. Data records and documents using XML are platform-independent and fully portable. With XML, exchanging data between incompatible systems is distinctly possible.
