Frequently Asked Questions

Find Quick Answers

What standards does the formatter follow?

It adheres to XML 1.0/1.1 parsing basics, preserves CDATA and comments, and formats according to user-specified options. It is not a full schema validator unless enabled.

Can I customize indentation and attribute wrapping?

Yes. You can choose indent_size (2 or 4), enable or disable attribute wrapping, and decide whether to preserve comments during formatting.

Will formatting alter content or namespaces?

No. Formatting only reserializes the document to a consistent style; element data, values, and namespace URIs remain unchanged.
