XSLT

XSLT (Extensible Stylesheet Language Transformations) is a W3C standard language for transforming XML documents into other formats such as HTML, plain text, or different XML structures. It uses template-based rules and XPath expressions to select and restructure XML data. The current version is XSLT 3.0, a W3C Recommendation since June 2017. XSLT is commonly used in data integration, document publishing, and enterprise data exchange pipelines. The primary production implementation is Saxon by Saxonica, which supports XSLT 3.0, XQuery 3.1, and XPath 3.1.
