Frequently asked questions
What counts as invalid XML here?+
Unclosed tags, mismatched tags, and malformed attributes all get flagged with a line reference.
Does this validate against a schema (XSD)?+
No, it checks that the XML is well-formed, not that it matches a particular schema.
Will formatting change the actual data?+
No, only whitespace and indentation change. Element order, attributes, and text content stay the same.
