Frequently asked questions
Does it validate XML syntax?
Yes. The tool checks whether the XML is well-formed and points to the relevant error when the parser hits an issue.
What happens with namespaces or malformed tags?
The validator surfaces the parse problem and preserves the original structure so you can fix the exact offending element or attribute.
Is untrusted XML executed?
No. The XML is parsed in-browser as text and never executed, so external entity processing is avoided.
Can I download the result?
Yes. After formatting or minifying, the output can be copied or downloaded as a .xml file.
