Extensible Markup Language (XML) is a markup language and file format used to define, store, and share data between computer systems. It establishes a set of rules for encoding documents in a format that is both human-readable and machine-readable, making it a software- and hardware-independent tool for data exchange. Unlike HTML, which focuses on how data looks, XML is designed to be self-descriptive and focuses on what the data is.
XML's flexibility makes it a cornerstone technology for thousands of applications, from everyday productivity tools to complex system configurations. It is primarily used to structure, store, and transport data across different systems, ensuring information can be shared and understood universally.
XML documents follow a strict, tree-like structure. Each document is built from elements, which are marked up by tags and can contain data or other nested elements. This hierarchical format ensures the data is well-organized and easily parsed.
While both are markup languages, XML and XHTML serve fundamentally different purposes in data handling and web presentation.
A wide range of tools exists for working with XML. Simple text editors can be used for basic editing, while specialized XML editors offer features like syntax highlighting and validation. For programmatic access, developers use APIs like SAX and DOM to parse and manipulate XML data, and languages like XSLT to transform it.
Adhering to best practices ensures your XML documents are robust, readable, and interoperable.
Isn't JSON now preferred over XML for most applications?
While JSON is often favored for web APIs due to its lightweight syntax, XML remains critical for enterprise systems and industries requiring strict schema validation. The choice depends on the specific use case, as each format has distinct advantages.
Is XML still relevant in the age of modern data formats?
Absolutely. XML's strict structure and validation capabilities make it indispensable for complex data interchange, configuration files, and industry standards like financial reporting (XBRL) and vector graphics (SVG). Its relevance is in specialized, structured data domains, not just general data transfer.
When should I use an attribute versus a child element?
Use attributes for metadata that describes the element itself, such as an ID or a unit of measurement. Use child elements for the core data or content the element contains. This practice keeps your data structure clear, logical, and easier to parse.
