XPath
Query language for navigating and selecting nodes in XML and HTML documents.
Also known as: XML Path Language
XPath is a W3C query language for addressing specific elements or attributes inside an XML or HTML document. The syntax resembles path notation, for example //div[@class="price"]/span, and returns exactly the nodes that match a condition. XPath underpins many tools in scraping, test automation, and XML processing.
How XPath is structured
An XPath expression starts at the root or any node and navigates via axes such as child, descendant, or parent. Predicates in square brackets filter by attribute, position, or text content. Functions such as contains, starts-with, or normalize-space allow complex evaluations that are hard to express with pure CSS selectors.
Practical tools
XPath is a standard tool in Selenium and Playwright for locating elements, in Scrapy for extracting data, and in XSLT for transformation. Excel and Power Automate can also use XPath to parse XML responses from web services. Pitfall: overly specific XPath expressions break on small DOM changes, so selectors should be deliberately chosen for stability.
Context in marketing work
In a marketing environment XPath mainly appears in teams that work with crawlers, competitor monitoring, or conversion testing. It also plays a role when connecting external data sources such as supplier feeds or public datasets. Anyone running regular data extraction benefits from a small XPath library of proven patterns.
