XPath (XML Path Language)
XPath is a query language used for selecting nodes from an XML document. It allows developers to navigate through elements and attributes in XML documents by specifying paths and conditions. XPath is widely used in conjunction with XSLT (Extensible Stylesheet Language Transformations) for transforming XML documents, as well as in XML parsing, validation, and manipulation tasks. It provides a powerful and flexible way to access and analyze XML data structures.
