XML (eXtensible Markup Language) is a markup language designed to store and transport data in a structured, human-readable format. It uses a system of tags and attributes to define data elements, enabling consistent data representation across platforms and systems.
Commonly used in web services, document management, and enterprise data exchange, XML supports interoperability between disparate systems. It is widely applied in industries such as finance, healthcare, publishing, and telecommunications for data integration, configuration files, and document standards like XHTML, RSS, and SOAP.
- Designing and validating XML schemas (XSD) for data structure
- Transforming XML documents using XSLT
- Parsing and processing XML with tools like DOM, SAX, or XPath
- Integrating XML with web services and APIs
- Ensuring compliance with industry-specific XML standards
Professionals with XML expertise are expected to understand well-formed and valid XML syntax, namespace handling, and schema definition. They often work alongside developers, data architects, and systems analysts to ensure data consistency and efficient information exchange. Knowledge of related technologies such as JSON, XPath, XQuery, and XML databases (e.g., BaseX, eXist-db) enhances proficiency. XML skills are essential in roles involving data integration, enterprise application integration (EAI), and legacy system modernization.
