Does this validate against an XSD schema?

No. Formatting checks basic well-formedness—balanced tags and parseability—not business rules encoded in XSD or Relax NG schemas.

Are namespaces preserved?

Prefixes and xmlns attributes remain on the elements where present. The formatter does not rewrite namespace URLs or canonicalize prefixes.

Can I minify XML too?

Where supported, minify removes non-essential whitespace between tags. CDATA sections and significant space inside elements should be reviewed manually after compression.

Readable XML for integrations that still speak SOAP

Enterprise billing and identity flows still ship XML payloads in tickets. Pretty-printing locally helps you find a wrong namespace or duplicated element before redeploying an integration that cannot be rolled back quickly.

Attribute and text nodes

Mixed content—elements with both child tags and text—formats conservatively to avoid altering semantic whitespace in schemas that treat text nodes as significant.

Security note

Never paste production private keys or patient data into any online formatter. Client-side processing reduces exposure but does not remove compliance obligations on your machine.
