Frequently Asked Questions
Does formatting change XML semantics?
Whitespace between tags is generally insignificant. However, whitespace inside text content is preserved. Formatting won't change data meaning for standard XML.
Can I minify XML too?
Yes. CipherKit's formatter includes a minify option that removes unnecessary whitespace for compact output.
Does this validate XML?
The formatter catches well-formedness errors (unclosed tags, invalid syntax). For full validation against schemas (XSD/DTD), use a dedicated XML validator.
