XML Escape

XML Escape provides a deterministic, client-side tool for transforming raw XML strings into escaped representations suitable for embedding in HTML attributes, JavaScript strings, or configuration files. It targets developers, QA engineers, data engineers, and content teams who need safe, repeatable output without server-side processing. The tool accepts a single input field containing an XML fragment or a full document and returns a consistent escaped result.

Core logic and rules: the transformation replaces characters with special meaning in XML (less-than, greater-than, ampersand, apostrophe, and quotation) with their corresponding entities (<, >, &, ', "). An optional mode converts non-ASCII characters to numeric references, enabling safe embedding in environments that require ASCII-only input. The implementation is stateless and deterministic, ensuring identical input yields identical output.

Use cases include embedding user-provided XML into HTML attributes, generating test fixtures, preparing strings for code templates, or exporting escaped data for transport. Outputs can be a plain escaped string for direct paste, or a numeric reference representation for strict encoding needs. The tool emphasizes correctness, speed, and predictable results across large strings.

Error handling and localization: the tool can validate well-formedness as a pre-check when enabled, returning specific error codes for malformed XML. Processing is offline and does not rely on external services. The behavior is consistent across locales, currencies, and time zones since escaping is locale-agnostic and focused on character-level safety.
