Questions
How do I pretty-print an XML document?
Paste your XML into the input and the formatter will add proper indentation and line breaks for each nested element, making the document tree structure clearly visible.
Will the XML formatter preserve CDATA sections and comments?
Yes, the formatter preserves CDATA sections, XML comments, processing instructions, and all attribute values exactly as they appear. Only whitespace between elements is adjusted.
Can I format SOAP or RSS XML with this tool?
Yes, the formatter works with any valid XML including SOAP envelopes, RSS feeds, Atom feeds, and SVG files. Namespaces and prefixes are preserved.
Does the XML formatter validate my document?
The formatter checks for well-formedness (matching tags, proper nesting) but does not validate against an XSD or DTD schema. Malformed XML will produce an error message.
