Learn About XML Programming Language


XML stands for Extensible Markup Language. It is a text-based markup language derived from Standard Generalized Markup Language (SGML).
XML tags identify data and are used to store and organize data, rather than specifying how to display it like HTML tags, which are used to display data. XML won't replace HTML any time soon, but it introduces new possibilities by adopting many successful HTML features.

There are three important characteristics of XML that make it useful in a variety of systems and solutions:


XML is expandable
XML allows you to create your own descriptive tag, or language, that fits your application.

XML carries data
don't serve it - XML ​​allows you to store data regardless of how it is presented.

XML is a public standard
XML was developed by an organization called the World Wide Web Consortium (W3C) and is available as an open standard.

Use of XML

What is Markup?

XML is a markup language that defines a set of rules for coding documents in a human-readable and machine-readable format. So what exactly is a markup language? Markup is information added to a document that enhances its meaning in certain ways, as it identifies the parts and how they relate to one another. More specifically, a markup language is a set of symbols that can be placed in the text of a document to demarcate and label parts of the document.

The following example shows how XML markup looks when embedded in a piece of text.


<message>

   <text>Hello, world!</text>

</message>


This snippet includes markup symbols, or tags such as <message> ... </message> and <text> ... </text>. The <message> and </message> tags mark the start and end of the XML code fragment. The <text> and </text> tags surround the Hello, world! Text.

Is XML a Programming Language?

A programming language consists of its own grammar and vocabulary rules that are used to create computer programs. This program instructs the computer to perform a specific task. XML doesn't qualify to be a programming language because it doesn't perform any calculations or algorithms. Usually stored in simple text files and processed by special software capable of interpreting XML.
