Frequently Asked Questions
What is XML?
XML (eXtensible Markup Language) is a markup language for encoding documents in a format that is both human-readable and machine-readable. It is used for data exchange, configuration files, RSS feeds, office documents (DOCX, XLSX), and more.
What is the difference between XML and HTML?
HTML is for displaying data and has predefined tags. XML is for storing and transporting data with user-defined tags. XML is stricter — all tags must be properly closed and nested, and attribute values must be quoted.
Can I validate XML with a DTD or XML Schema?
This tool validates XML well-formedness — proper tag nesting, closing tags, and encoding. For full DTD or XML Schema (XSD) validation, you need a more specialized XML validator.
