Frequently Asked Questions

Does the formatter validate my XML?

Yes. The formatter checks for well-formedness including matching tags, proper nesting, valid attribute syntax, and correct character encoding. Errors are reported with line numbers to help you fix issues quickly.

Can I format SOAP messages and web service responses?

Absolutely. SOAP messages are standard XML documents. Paste the entire SOAP envelope and the formatter will indent all elements including headers, body, and namespaced tags.

Does formatting change the content of my XML?

No. The formatter only adjusts whitespace between tags. Element values, attributes, CDATA content, and namespace declarations remain unchanged.
