About This Tool

XPath extractor online is a purpose-built evaluation engine that accepts XML or HTML content and an XPath expression to return matches. It is used by developers, data engineers, QA analysts, and web scrapers who need precise data from complex documents without coding a parser.
Conceptually, the tool parses the input into a DOM-like structure and applies the supplied XPath to identify nodes, attributes, or values. Results can be returned in structured formats, such as JSON arrays or serialized fragments, to fit integration pipelines.
Core value and differentiators: immediate evaluation in the browser or serverless environment; no setup; supports namespace handling when configured, robust error reporting for invalid syntax or data, and flexible result formatting that scales from single values to large result sets.
Core features include input validation, sample XPath snippets, support for XPath functions (contains, starts-with, text()), and multiple output formats (JSON, XML, CSV). Typical use cases include extracting article titles, links, attributes, and data fields from web pages or XML feeds, validating selectors in test fixtures, and feeding downstream analytics pipelines.

How to Use

  1. Provide inputs: paste or upload XML/HTML content and specify the XPath expression.
  2. Choose options: indicate whether the document is XML or HTML and, if needed, set a namespace mapping.
  3. Run evaluation: submit the inputs to execute the XPath query and generate results.
  4. Review outputs: inspect matched nodes/values, and use export options to download JSON, XML, or CSV.
  5. Iterate: refine the XPath expression and re-run as needed.

Frequently Asked Questions

Find Quick Answers

What documents are supported?
The tool accepts well-formed XML and HTML documents; it uses a standard DOM parser and XPath evaluation; if HTML is not well-formed, forgiving parsing may be used, but behavior is consistent with DOM rules.
Can I use namespaces?
Yes, provide a namespace mapping to resolve prefixed names in XPath expressions; if not provided, prefixed names will not match and may yield no results.
How are results formatted?
Results are returned as a JSON array of matched items, including values and paths; you can export as JSON, XML, or CSV to fit your data pipeline or testing framework.
Is there a size limit?
Input size is constrained by the hosting environment; for very large documents, chunking or streaming approaches are recommended; extremely large responses may be trimmed to preserve performance.
