What Is XML?

A friend asked me earlier, what is XML? Well, he’s a blogger and he probably met this term most of the time as it’s all over the web that’s why I wonder why he don’t know it’s meaning and the importance of it.

XML is short for Extensible Markup Language made to transport structured data across different systems and platforms.

I remember an article from W3C pointing out the following things:

  • XML is for structuring data
  • XML looks a bit like HTML
  • XML is text, but isn’t meant to be read
  • XML is verbose by design
  • XML is a family of technologies
  • XML is new, but not that new
  • XML leads HTML to XHTML
  • XML is modular
  • XML is the basis for RDF and the Semantic Web
  • XML is license-free, platform-independent and well-supported

This supports the explanation that xml was created to manage uses of structured data in the web. RSS is a good example of a modified xml format which carries headlines and contents of your blog.

Also note that xml is not replacing html, it is for describing the data and its structure while the latter focuses on how data looks.
