XPath Tester for XML: Test XPath 1.0 Expressions Online
The XPath Tester lets you evaluate XPath 1.0 expressions against XML directly in your browser, using its native document.evaluate method. Map namespace prefixes, use one of four result types—nodeset, string, number, or boolean—and inspect matched nodes with their serialized content and XPath. Test a query against real XML and refine it before using it in an application.
The XPath Tester is a browser-based tool for evaluating XPath 1.0 expressions against XML. It uses the browser's native document.evaluate method, so you can test a query and inspect its result without first building it into an application. The tester supports namespace prefix mapping and can return nodeset, string, number, or boolean results.
When XML uses namespaces, provide a mapping for the prefixes used in your XPath expression. Choose the result type that fits what you want to evaluate: nodeset results show matched nodes with their serialized content and XPath, while string, number, and boolean results return those respective types. The result you see depends on the expression and the XML you provide.
XML represents structured data using elements, attributes, and text; XPath is a language for selecting or evaluating parts of that data. Testing XPath against XML helps you check what a query selects or returns before using it in code. The two work together: XML is the document being queried, and XPath describes the selection or evaluation.
The XPath Tester runs entirely in your browser. Your input is processed on your device and is not sent to a server, and the tool works offline once the page has loaded. It is useful for developers and DevOps engineers who want to try a query, inspect its results, or refine an expression against XML without setting it up in an application first.
Step 1: Paste or drop in your XML content. This gives the tester the document that your XPath expression will be evaluated against.
Step 2: Enter the XPath 1.0 expression you want to test. Use the expression to select nodes or evaluate a string, number, or boolean result.
Step 3: If your XML uses namespaces, provide a namespace prefix mapping. This lets your expression use prefixes to refer to namespaced elements.
Step 4: Review the result. For nodeset results, inspect the matched nodes along with their serialized content and XPath.
Use case: Try an XPath expression against real XML and see which nodes it matches before adding the query to your code.
Use case: Iterate on an expression without saving a file or wiring it into your application first.
Use case: Check how an expression behaves for edge cases before you ship it.
Use case: Test namespace-prefixed XPath queries against XML that uses namespaces by providing a namespace prefix mapping.
Use case: Inspect matched nodes and their serialized content to understand what a nodeset expression selects.
Use case: Check string, number, or boolean results when you need to evaluate a value rather than inspect a set of matched nodes.
