XSLT (Extensible Stylesheet Language Transformations)
XSLT is a language for transforming XML documents into other XML documents or different formats such as HTML, plain text, or other markup languages. It uses XPath to navigate and match parts of an XML document and defines rules on how to handle each node. XSLT is essential for data presentation and manipulation, allowing the separation of content from presentation and enabling the reuse of XML data across different applications and platforms.
