XSD Viewer

Purpose-built for developers and QA teams, this tool validates XSD schemas and checks XML samples against schema constraints. It parses XSD content, resolves imports, and extracts the schema graph of elements, types, and attributes to support quick quality checks. When provided with an XML instance, the validator reports precise mismatches, path locations, and constraint violations. The resulting schema summary highlights complexity, element counts, and potential hotspots, aiding design decisions and documentation. Conceptually, it treats the XSD as a graph of nodes (elements/types) and edges (relationships), enabling deterministic error reporting and reproducible validation results. The tool is valuable in API design, data contract testing, and CI workflows where schema conformance is critical, and it supports exporting results for integration with other tooling.

Unique value lies in combining structural visualization with strict schema validation, all aligned to W3C XML Schema standards. It operates offline on provided content, supports xs:import and xs:include handling when locations are accessible, and delivers actionable feedback without relying on external services. Use cases include validating schema evolution, ensuring XML payload compatibility across services, and generating human-readable reports for compliance and testing teams.

Core features include: XSD parsing, structural summary, import/namespace resolution, optional XML instance validation, detailed error reporting, and export of results. Practical outcomes are faster debugging, clearer data contracts, and higher confidence in XML-based integrations.
