XML is a text-based markup programing language derived from Standard Generalized Markup Language (SGML). The viewer or editor primarily uses XML Editor applications to view or modify XML tags. XML stands for Extensible Markup Language. So, It is a markup language that humans, as well as machines, can understand.

If you are a developer and have worked with XML before, you already know many editing applications are available. You can select any editor and use Syntax Highlight and XML Format plugins that allow you to edit XML easily.
