Acerca de Validador XML
Validate XML documents
Well-formed XML has correctly nested elements, quoted attributes, one document root, and valid syntax. That is different from schema validation: a document can be well formed while still failing an application-specific XSD or business rule.
Cómo usar esta herramienta de desarrollo
- Paste the XML document into the validator.
- Run validation and go to the reported line and column when a parse error appears.
- After syntax is valid, run the schema or application checks required by the system that will consume the document.
Privacidad y tratamiento de datos
XML parsing runs locally and does not intentionally fetch external entities or resources. Use a reduced sample when the document contains personal data or credentials.

Preguntas frecuentes
Does valid XML mean the data is correct?
No. This tool checks syntax and well-formedness. Required fields, types, namespaces, and business rules need separate validation.
Why is the error reported after the real mistake?
A missing quote, closing tag, or delimiter can make the parser lose its place; inspect the reported location and the preceding markup first.
Does the validator load external entities?
The browser-side workflow is designed for local parsing without external resource requests. Still avoid unknown documents and review the page's processing notice.
