About This Tool

XPath Tool Online provides rapid XPath evaluation against XML/HTML documents to retrieve matched nodes or string values. It supports standard XPath features and optional namespace mappings to resolve prefixed names. Conceptually, the tool parses the document into a tree, applies the query, and returns results in a deterministic order suitable for automation and verification. Users benefit from immediate feedback on query correctness, reduced debugging time, and a reliable path mechanism for data extraction and content auditing. Core value lies in accuracy, speed, and namespace awareness, enabling consistent data mapping and test automation across SEO, publishing workflows, and data engineering tasks. Core features include input of document and XPath, optional namespace declarations, and configurable output formats (node lists or string values). Use cases include extracting title or meta elements in SEO audits, validating specific DOM paths in automated tests, or feeding XPath results into JSON pipelines for downstream processing.

How to Use

  1. Provide inputs: paste the XML/HTML document and the XPath expression in the designated fields.
  2. Optionally supply namespace mappings for prefixed names.
  3. Run evaluation to generate results.
  4. Review results: count, node values, or string results; adjust expression if needed.
  5. Export or copy results for downstream workflows.

Frequently Asked Questions

Find Quick Answers

What can I evaluate with this tool?
You can evaluate a valid XPath expression against a provided XML or HTML document and receive either a list of matched nodes or their string values. The tool supports common axes, predicates, and namespace resolution for accurate results.
How are namespaces handled?
If your XPath uses prefixes, supply a namespace map of prefix to URI. The evaluator resolves prefixes against the provided URIs, enabling correct matching in documents with multiple namespaces.
What formats are outputs?
Outputs can be a node list or a set of string values, depending on the expression and options. The tool can also provide a count of matches and an explicit error object if evaluation fails.
What if the XML is malformed or the XPath is invalid?
The tool returns a structured error with a descriptive message and, when possible, position hints to aid debugging. It avoids crashing and provides actionable details.
