Extensible Markup Language (XML)

A coding language, both human- and machine-readable, that enhances the structure, meaning, or context of a text document is known as Extensible Markup Language (XML). XML can vary from straightforward to intricate, hence its designation as “extensible.” Notably, the present iteration of HTML serves as a specialized instance of XML. Schema markup exemplifies how XML can be leveraged to enhance the user experience (UX) of search engine results pages (SERPs).


An example of Extensible Markup Language (XML) could be a document used to store and transport structured data, such as an RSS feed. In XML, data is enclosed within tags that define its structure and meaning. For instance, a basic XML document might contain tags like <title>, <description>, and <link> to denote the title, description, and link of each item in the feed.

This structured format allows software applications to parse and process the data effectively, making XML a versatile choice for representing and exchanging information across different platforms and systems.
