XPath/CSS Selector Tester

Test XPath and CSS selectors against HTML with real-time highlighting, file upload, and advanced features. The best selector testing tool for developers.

XPath/CSS Selector Tester brings reliable extraction and inspection to your scraping and QA workflows. Preview matches in real time, study element hierarchies, and export results for downstream processing.

Key features

  • XPath selector testing with real-time validation

How it works

Paste HTML, enter a CSS or XPath query, and see matches annotated in the preview. Premium enables file/URL input, batch testing, and CSV/JSON export for large‑scale analysis.

  1. Load sample HTML or paste your own.
  2. Enter a CSS/XPath query and review highlighted nodes.
  3. Copy matches or (premium) export to CSV/JSON.

Examples

List article titles

article h2

Find links containing “docs”

//a[contains(., 'docs')]

Extract href attributes

//a/@href

Security & privacy

Where applicable, processing runs locally in your browser. Inputs are not logged or sent to external services. Premium features inside the app use Supabase Auth to protect access. For sensitive work, prefer local files and avoid sharing secrets. Outputs include copy and download actions to minimize manual transcription errors.

Accessibility

The tool supports keyboard navigation and screen readers with ARIA labels and descriptive messages. Focus order is logical, and error messages use human‑readable language. These docs maintain proper heading hierarchy and color contrast, and the app version includes skip links and live regions where appropriate.

Limitations & disclaimers

Some advanced capabilities are available only in the DevToolsHub app with a premium plan. The static documentation does not execute code or store inputs. Where behaviors differ across runtimes (browsers, servers, language engines), treat outputs as representative and verify against your production stack when correctness is critical.
