Frequently Asked Questions
XML vs JSON formatting expectations?
XML cares about declaration, namespaces, and mixed contentu2014beautifiers indent tags but do not infer schema constraints. Invalid XML stays invalid until you fix mismatched tags or illegal characters.
Why does validation u201cpassu201d visually but fail in production?
Pretty layout is not XSD validation. Your service may enforce namespaces, attribute order for signatures, or forbidden characters (``). Use `xmllint` or IDE validators tied to your schema.
Large SOAP or RSS feeds?
Multi-megabyte feeds can freeze the tab; prefer streaming CLI formatters for CI.
Security?
Never paste confidential integration XML on a shared screen; local processing still leaves traces in clipboard managers.
Entities and CDATA?
CDATA sections protect literal `]` sequences for docs; the formatter preserves segments it recognizes but exotic PI nodes deserve spot checks.
Minify toggle mindset?
Some servers need compact XML for bandwidth; others need human diffabilityu2014pick per environment.
