A markup language that defines rules for encoding documents in both human-readable and machine-readable format.XML is a markup language intended to enable people and robots to read it. XML for Extensible Markup Language is brief and defines rules sets that encode different texts. It’s very similar to HTML, but there are variances – the biggest difference is their purpose.
XML was intended to convey data and concentrate on what data is. HTML was created to show data and emphasis on its appearance. XML is used for data description. The XML standard allows for flexible formats and structured data electronically shared across the public Internet and corporate networks. The XML code, formal W3C recommendation, is identical to Hypertext Markup Language (HTML). Both XML and HTML contain page and file content markup symbols.
HTML code describes how a webpage’s content (mostly text and graphic images) is displayed and interacted. The data structure in XML is known as self-description or self-defining, which implies that when data enters, there is no need to pre-build the structure to store the data; it is understood dynamically within XML. Any individual or corporation who wishes to share information uniformly may utilize the XML format. An element described by tags is the fundamental building unit of an XML document. An element has a start and end title.
Every element in an XML document is an outermost element called the root element. This feature enables XML to handle hierarchy structures. An XML document (which can be read and interpreted by an XML parser) is deemed "well-formed" if it complies with the XML specifications, it is correctly marked up, and the elements are properly nested. XML also enables defining element attributes and describing element characteristics in an element’s starting tag. The XML applications are infinite. For example, computer manufacturers might agree upon a standard way to express computer product information (processing speed, memory size, and more) and then write XML code for the product information format. This traditional manner of describing data allows a user to send an intelligent agent (software) to the websites of each computer maker, acquire data, and then compare it validly.
The power of XML lies in its simplicity. It may take big pieces of evidence and amalgamate them into an XML document, significant parts that provide the material with structure and organization.
