What is XML?
XML (Extensible Markup Language) is a flexible, text-based format for representing structured data using custom tags, widely used for data exchange between systems, configuration files, and document storage.
How Does Xml Work?
XML allows developers to define their own tags and document structure, making it a versatile format for representing virtually any type of data. It is both human-readable and machine-parsable, with strict syntax rules that ensure data integrity. XML is used extensively in web services (SOAP), RSS feeds, sitemaps, configuration files, and as an interchange format between different software systems.
In web hosting, XML appears in many contexts such as sitemap.xml files that help search engines discover pages, RSS feeds for content syndication, and server configuration files. While JSON has become the preferred format for many web APIs due to its lighter syntax, XML remains essential in enterprise environments and legacy systems where its schema validation and namespace features are required.
