The whole truth about XML: From history
Back in 1969, one of IBM ’s development teams developed a generalized markup language ( Generalized Markup Language - GML ), which was used to exchange official documents in law firms.
In 1974, Charles Goldfarb transformed GML into a new universal markup language called Standard Generalized Markup Language ( SGML ), which ISO adopted in 1986, referring to its complexity.
By setting the task to simplify SGML for use in Internet technical documents, Tim Berners-Lee and Anders Berglund created HTML .
Finally, it was only in 1998 that the W3C agreed to introduce a new standard Extensible Markup Language ( XML ), an extensible markup language . XML is a text format storage structured data. Its purpose was to ensure compatibility when transferring structured data between different information processing systems, especially when transmitting such data over the Internet. Now the Internet has a whole family of XML formats for data transfer, such as RDF, RSS, MathML, XHTML, SVG .

XML looks like HTML at first glance, but its main feature is the ability to create your own set of tags. Therefore, it can be used to create your own markup language.
The main advantage of XML is that it is a text document containing data and markup tags used to describe the data. An application that works with an XML document extracts data from it using parsing.
