Lenguajes de marcas para la gestión de contenidos y la publicación Web (debate)

First and foremost, we would like to explain the terms involved. Being both markup languages, on  the  one  hand,  HTML  stands  for  “Hyper  Text Markup  Language”,  and  on  the  other,  XML stands for “Extensible Markup Language”.
 
Focusing on  the differences, XML points at  the  structure of  the  information, saving  time and simplifying  the  software,  not  requiring,  consequently,  DTD  or  Document  Type  Definition. Besides,  it supports Unicode, allowing almost any  information  in any written human  language
to be communicated, and in addition, it doesn’t have any data. HTML however, requires from the authors  to avoid  the use of presentational markup as well as  to  use available markup  to differentiate  the  meanings  of  phrases  and  structure  in  the  document.  Moreover,  HTML documents are more difficult to be delivered, as they are normally delivered either over HTTP servers or through e-mail.
 
In short, XML is more useful than HTML not only because it is easier to try for the computer programs, but also because HTML does not indicate what it is representing. In fact, HTML is known for describing the content of what it labels.
