XSLT 3.0
XSLT 3.0 is a declarative programming language used for transforming XML documents into other formats, such as HTML, XML, or plain text. It is part of the XSL (Extensible Stylesheet Language) family and is standardized by the W3C, offering advanced features like streaming, higher-order functions, and JSON support. This version enhances performance and flexibility compared to earlier iterations, making it suitable for complex data processing tasks.
Developers should learn XSLT 3.0 when working with XML-based systems, such as in publishing, data integration, or web services, where efficient transformation of structured data is required. It is particularly useful for scenarios involving large XML files, as its streaming capabilities reduce memory usage, and its support for JSON allows integration with modern web APIs. Use cases include generating reports, converting data formats, and implementing content management systems.
