Online XPath Generator

An online XPath generator accepts an HTML or XML document and an optional context node, then returns robust XPath expressions tailored to the specified context. It targets developers, QA engineers, data scientists, and automation engineers who need repeatable selectors for web scraping, DOM verification, or data extraction. The tool emphasizes correctness, determinism, and compatibility with standard XPath syntax across common document structures.

Conceptually, the tool parses the document into a DOM/XML tree, identifies the context node, and applies XPath construction rules that favor concise, unique paths. It supports absolute and relative paths, attribute-based restrictions (id, class, data-*) and axis relations (child, descendant, ancestor). Namespace handling can be enabled or mapped for XML documents.

Unique value and features include explicit namespace support, multiple output forms, and the ability to generate several candidate expressions when a single path is ambiguous. The tool also validates that the produced XPath would select the intended node in the provided sample, and it can produce explanations of trade-offs between paths.

Use cases span data engineering, test automation, and documentation of DOM queries. Users can export expressions to scripts, paste them into selectors in test frameworks, or share them with teammates to ensure consistent selector logic across environments.
