Frequently Asked Questions
Is validating XML with PDFPilot really free?
Yes. XML Validator is completely free to use, with no sign-up or account required.
Are my files uploaded to a server?
No. The validation runs entirely in your browser using DOMParser. Your file is never uploaded to PDFPilot's servers.
Does this check against an XML Schema (XSD) or DTD?
No — this checks well-formedness (correct tag nesting, matching open/close tags, valid syntax), not validity against a specific schema. It won't catch a document that's syntactically correct XML but doesn't match your particular schema's rules.
Does this download anything?
No — this tool just checks well-formedness and shows the result on screen. Use XML Formatter if you also want a downloadable, cleanly-indented copy.
