XPath
XPath is a language used to navigate through elements and attributes in an XML document. It allows users to select nodes or a set of nodes based on various criteria, making it easier to extract specific data from complex structures.
By using XPath expressions, developers can efficiently query and manipulate XML data. This is particularly useful in web development, data processing, and applications that rely on XML for data interchange, as it simplifies the task of locating and retrieving information within the document.
