Fonctionnement et fonctionnalités

Validate XML markup against W3C well-formedness standards using browser DOMParser. Identifies unclosed tags, attribute syntax flaws, and line-level error locations.
Step 1
Paste or Input Data
Enter code, tokens, queries, or raw strings directly into the client-side editor workspace.
Step 2
Instant Browser Processing
Native Web APIs and in-browser parsers execute deterministic conversions with zero network latency.
Step 3
Inspect and Export
Copy formatted outputs or download clean data files with one click, knowing your input never left your device.

Fonctionnalités clés

  • W3C well-formed XML check
  • Tag balance & closing verification
  • Precise line/column error diagnostics
  • Node count and tree statistics

Considérations techniques et limites

  • Zero-transmission privacy: data processing runs strictly client-side inside your browser environment. Source code, secrets, and payloads are never dispatched to external servers or telemetry systems.
  • La vitesse de traitement dépend du matériel de votre appareil (processeur et mémoire RAM). Les fichiers de plus de 200 Mo peuvent dépasser la mémoire du navigateur.
