XSLT Functions

XSLT functions are tools within XSLT (Extensible Stylesheet Language Transformations) that help manipulate and transform XML data. Think of them as specialized operations—like calculations, text processing, or data formatting—that are used to extract, modify, or analyze parts of an XML document. For example, they can sum numbers, format dates, or retrieve specific elements. These functions make it easier to convert complex XML structures into different formats, such as HTML or plain text, enabling better data presentation and integration across applications.
