How to use XML Formatter
Make compact XML easier to inspect or remove presentation whitespace when a smaller source representation is needed.
XML handling
- Element nesting, names, attributes, entities, comments, CDATA sections, and processing instructions are checked.
- Text-only elements remain inline so their text content is not changed by formatting.
- DOCTYPE declarations are rejected and external entities are never resolved.
Frequently asked questions
Does formatting change XML text values?
Text-only elements remain inline, while indentation-only whitespace between child elements is normalized.
Why are DOCTYPE declarations rejected?
Rejecting DOCTYPE avoids external-entity and document-type processing in this focused formatter.
Can I minify XML?
Yes. Minify removes presentation whitespace between structural nodes while preserving meaningful text and markup.
