Frequently Asked Questions
How do I validate XML?
Paste your XML and click Validate. The tool checks for well-formedness (proper tag nesting and closing). Full schema validation (XSD/DTD) is not included.
What is the difference between XML and HTML?
XML is strict — all tags must be closed and properly nested. HTML is more lenient. XML is used for data exchange, config files, and APIs like RSS and SOAP.
