The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, data, configuration, books, transactions, invoices, and much more. It was derived from an older standard format called SGML (ISO 8879), in order to be more suitable for Web use.

What is XML and CSS?
XML uses markup to describe the structure and data content of a document, making it easy both for authors to write it and for computer programs to process it. CSS, on the other hand, makes it possible to present that document to the user in a browser.If CSS works well with HTML, it will work wonders with XML.
