XML Formatter FAQ
No — only whitespace and indentation are modified. Element names, attribute values, and text content are preserved exactly.
Yes — RSS, Atom, and any other XML-based feed formats are fully supported.
The formatter preserves the XML declaration at the top of the document. It will still properly indent all following elements.
The formatter will show an error if the XML is malformed (e.g. unclosed tags or missing quotes). It is a beautifier, not a full schema validator, but it catches common structural issues.
