Frequently Asked Questions
It parses your input with the browser's built-in DOMParser and checks for a parsererror node. If none is found, it reports the root element name and its direct child count as confirmation.
No — this only checks well-formedness (correct tag nesting, closing, and syntax), not validity against a schema. There's no XSD/DTD-aware validation here.
No — namespace and ID-uniqueness rules are schema/DTD-level concerns, not covered by a well-formedness check. This tool only confirms the tags are properly opened, closed, and nested.
No — parsing happens entirely in your browser using DOMParser; nothing is uploaded.
