XPath
A lantern illuminating the paths through the labyrinthine world of XML documents, XPath is a powerful language that enables the precise location and extraction of information from within the intricate structures of XML data.
Example
Imagine an XML document containing information about a collection of books, including titles, authors, and publication dates. To retrieve a list of all the book titles, a developer can use an XPath expression like "//book/title". By providing a clear and efficient way to navigate the XML document, XPath simplifies the process of accessing and manipulating data within complex structures.
