XML, or Extensible Markup Language, is a coding language that is one of the friendliest languages for those who do not speak English due to its flexibility. It can easily be read and interpreted by both humans and computers, which makes it pretty unique. You may not even know it, but if you subscribe to an RSS feed, you are already interacting with XML. Financial institutions use this language regularly, as do news organizations and even weather reporting groups because manages massive amounts of data in a very efficient manner. The basic function of XML is to store data in a very organized fashion and deliver to a destination intact. XML often works together with HTML to create the front-end experience. XML tells the page what is going to go on it, and HTML tells everything how to look. However, XML and HTML have some serious differences.
With HTML all of the defining tags are pre-defined. If you put in your own tag or even just make a spelling mistake, your code won’t take and you’ll be disappointed. With XML, users can define their own tags through documentation. XML can be used for many different purposes including easily transporting data from older systems into newer ones.
XML is also a bit more sensitive than HTML, because its tags are not pre-defined, the makers wanted to be sure that developers say what they mean. So, the tags are case sensitive, and they must be put in the proper order with closing tags. HTML can be a bit more forgiving in those departments.
Overall, XML is a powerful tool in any developer’s pocket because it can be easily interpreted by anyone. It can be useful for speech to text applications, RSS feeds and more. Developers and data scientists who need to interpret large amounts of data efficiently with minimal resources and maximum speed use XML often.
