About This Tool

The XPath parser online evaluates XPath expressions against XML/HTML content to extract data. It is designed for developers, QA engineers, data engineers, and integrators who need fast, repeatable data extraction from semi-structured documents.
Conceptually, the tool parses the XML into a tree, resolves any declared namespaces, and evaluates the XPath expression against the tree. The result is a collection of nodes, strings, numbers, or booleans, returned in a JSON-friendly format. Advanced features support namespaces and predicates.
Core value lies in quick validation of queries, exploration of document structure, and deterministic outputs for automation. It supports multiple matches and scalar results, making it suitable for scraping, testing, and transformation planning.
Core features include built-in XML parsing, XPath evaluation, optional namespace mapping, and consistent result formatting. It is lightweight, with no setup required and no dependencies beyond the browser or runtime environment. Users benefit from immediate feedback to refine queries, compare results across documents, and integrate results into pipelines with minimal scripting.

Frequently Asked Questions

Find Quick Answers

What XPath versions are supported?

The tool supports XPath 1.0 core features by default, including predicates and common functions. Advanced engines may offer experimental 2.0 features in some deployments; check the engine configuration if available.

Can I use namespaces in my XML document?

Yes. Provide a namespaces map to resolve prefixes used in the XPath expression. The parser applies the map during evaluation, enabling correct namespace-aware querying.

What happens if the XML is malformed?

Malformed XML results in a parse error with diagnostic details. The tool does not attempt to recover from structural errors; you should fix the XML and re-run the evaluation.

How are results returned for multiple matches?

If multiple nodes match, the tool returns an array of results. Each entry includes either the node's text content or its string representation, depending on the expression.
