Frequently Asked Questions
What does it validate?
Well-formedness: proper nesting, matching tags, valid attributes, proper encoding declaration, and XML syntax rules.
Can it handle large XML files?
Yes. Processing happens in your browser, so it depends on your device. Most modern devices handle files up to several MB.
Does it support namespaces?
Yes. XML namespaces are preserved during formatting. Namespace prefixes and declarations remain intact.
