XML Analyzer

The tool validates XML documents for well-formedness, namespace correctness, and optional schema conformance. It reports parsing errors with precise line and column locations and can return a concise validation status plus a structured error list. XPath evaluation is supported, allowing users to extract values, test node sets, and compare results across documents. The outputs are designed to be machine-readable for automation and human-readable for debugging.
Conceptually, the workflow consists of parsing the input document, optionally loading an external schema (XSD/DTD) if provided, performing type and structure checks, and resolving namespaces. If a schema URL is supplied, the tool fetches it (subject to policy) and applies its constraints during validation. XPath queries are evaluated against the validated document, returning values or node references with clear indications of the match context.
Who benefits: software engineers integrating XML APIs, data engineers validating feeds, and QA teams verifying configuration files. It supports local and remote schemas and is suitable for CI pipelines and data validation tasks. The tool's configuration is explicit and auditable, ensuring reproducibility across environments.
Unique value lies in precise error reporting, deterministic results, and flexible inputs (inline XML, schema URL, batch capability). It avoids transforming the input and focuses on analysis, validation, and query results. Use cases include pre-deployment checks, data feed validation, and documentation quality assurance.
