Does the formatter validate XML?
The browser's built-in DOMParser checks for well-formed XML. If your XML has errors (unclosed tags, invalid characters), an error message is shown.
What indentation does it use?
The formatter uses 2-space indentation by default.
Is my data sent to a server?
Formatting runs entirely in your browser using the native DOMParser and XMLSerializer. No XML is transmitted anywhere.
What is the difference between XML and HTML?
XML is a strict, self-describing markup language where you define your own tags. HTML has a fixed set of tags with relaxed parsing rules. Valid XML must have a single root element and all tags must be properly closed.
Can I minify XML?
The Minify option removes all whitespace between elements, producing compact XML suitable for transmission.
