XML Editor XPath

An in-browser XML editor with integrated XPath evaluation. Users paste or load XML, enter an XPath expression, and receive immediate results. The tool supports basic namespace mappings so expressions can target elements and attributes within XML namespaces. Conceptually, XML is parsed into a tree, the XPath is compiled, and a query traverses the tree to collect matching nodes, strings, numbers, or booleans. Results can be formatted as XML or plain text, and can be exported as XML, JSON, or CSV for reuse. This is beneficial for developers validating data extraction, QA engineers scripting test checks, and data analysts parsing configuration or payloads from APIs or files. Unique value comes from real-time feedback, clear error messaging about syntax or namespace conflicts, and straightforward namespace handling in a lean, browser-based environment with client-side processing. Core features include: XML parsing with well-formedness checks, XPath evaluation with support for standard axes and functions, namespace mappings, multiple result formats, and simple export options. It also supports optional pretty-print formatting of results and a lightweight validation mode that checks the resulting nodes for common patterns. Use cases include verifying XML API responses, extracting fields for data pipelines, debugging complex queries against stored XML documents, or validating transformations in configuration files. The tool is designed to work offline in the browser, preserving user data in session context unless explicitly exported, and providing helpful hints when expressions reference missing nodes or invalid paths.
