What is XML?
XML (Extensible Markup Language) is a markup language designed for storing and transporting data. It was created by the World Wide Web Consortium (W3C) in 1996 as a simplified subset of Standard Generalized Markup Language (SGML). XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable, making it ideal for data exchange between different systems and platforms.
File Format: XML files use .xml extension and consist of plain text with tags enclosed in angle brackets (< and >). Files are typically encoded in UTF-8 and can be opened with any text editor.
Structure: Uses a hierarchical tree structure with elements, attributes, and text content. Every XML document must have a single root element that contains all other elements. Documents must be well-formed and properly nested.
Syntax: Tags are case-sensitive and must be properly closed. Elements can have attributes providing additional information. Special characters like <, >, &, quotes, and apostrophes must be escaped.
Validation: XML can be validated against Document Type Definition (DTD) or XML Schema (XSD) to ensure it conforms to a specific structure and set of rules.
Extensibility: Unlike HTML with predefined tags, XML allows users to create their own custom tags and document structures, making it extremely flexible for various applications.
