Extensible Markup Language (XML), which has been present since the late 1990s, is still a popular and significant language for the creation of online applications. XML was first proposed in 1996 by the World Wide Web Consortium (W3C) and was created to provide a more intuitive way of communicating between different systems.

It was designed to be easily readable by both humans and machines and to be able to represent data in a consistent manner. XML has become the go-to language for data exchange between applications, as well as for creating web pages.

In addition to being used to describe the structure of data, XML can also be used to store and transport data. It is a flexible language and can be used to store text, numbers, images, audio, and video. XML documents can be written in a variety of languages, including HTML, XHTML, and SVG.

Working of XML

XML consists of elements, which are the basic building blocks of XML documents. Each element consists of a start tag, an end tag, and the content between the tags.

The start tag and end tag are used to mark the beginning and end of an element, while the content between the tags is used to provide additional structure and meaning to the element. Considering XML example, an element might include a title, date, and body of content.

XML also uses attributes to provide additional information about an element. Attributes are name/value pairs that are used to further define an element. Considering another XML example, an element might have an attribute that specifies the language of the content.

Even, XML also contains namespaces to provide a way to group elements together. Namespaces are used to group related elements and provide a way to avoid name collisions between elements from different sources.

An XML schema, which is an XML document that specifies the structure and content of an XML document, may be used to validate XML documents. To make sure the information in an XML document is correct and complies with a set of standards, an XML schema can be employed.

It can be used to store data in a database. XML documents can be stored in a database and retrieved using an XML query language. XML data can also be used to generate dynamic web pages.

XML is a versatile language that can be used for a variety of purposes. It is used to describe and structure data, provide additional information about an element, group elements together, validate data, transform data, and store data in a database. It is a powerful and flexible language that is used in many different applications.
