XPath (XML Path Language) is a query language used for navigating and querying XML documents.
• It provides a way to identify and extract data from XML documents by defining paths to elements and attributes within the document’s hierarchical structure.
• XPath contains over 200 built-in functions
• XPath is widely used in various XML-related technologies, such as XSLT (eXtensible Stylesheet Language Transformations) and XQuery.
Key features of XPath:
- XPath allows you to navigate through the hierarchical structure of an XML document using a path-like syntax.
- XPath defines different types of nodes, including element nodes, attribute nodes, text nodes, processing instruction nodes, and others.
- XPath expressions are used to define paths that locate specific nodes or sets of nodes within an XML document.
- XPath supports both absolute and relative paths.
