I recently finished teaching an XML class, and was reminded of the importance of this language that is used behind the scenes and not talked about or considered cool. There are so many systems that communicate digitally that use this language but we never hear about it in the media. XML is one of those workhorse languages that does its thing behind the scenes day after day allowing totally different systems to communicate with one another. XML allows data to be moved and rearranged into different formats for use in various systems. The language can be parsed and converted into other formats for web viewing. Thousands of different systems send this language around the internet everyday. It is a silent quiet language doing its thing allowing data to flow automatically. Nothing sleek or shiny about it so it is not discussed. Whether it is formatting data into standards that abide by specific formatting rules to conform to regulatory standards or simply allowing data to flow, XML does its thing. What an interesting & dependable language.
