XPath (XML Path Language) is a query language designed to navigate and extract data from the hierarchical tree structure of an XML document. Think of XPath as a GPS or a file system path (like C:/Documents/Invoices) for your data. It allows you to point exactly to the elements, attributes, or text you need without writing complex parsing code.
XPath is widely used in web scraping, software test automation (like Selenium), and data transformation pipelines. Core Concepts: The XML Tree Structure
XPath views an XML document as a tree of nodes. To understand how to navigate it, let’s look at a simple XML example representing a bookstore catalog:
In this XML structure, bookstore is the root element. The book elements are children of bookstore, and siblings to each other. The text The Hobbit is a text node, and category=“fiction” is an attribute node. Basic XPath Syntax
XPath uses path expressions to select nodes or node-sets. The most common symbols you will use as a beginner include: XPath Syntax – W3Schools
