About XML Formatter

The XML Formatter turns dense XML into readable markup, validates basic structure, and can minify documents when you need compact output.

Common uses

Format SOAP envelopes or RSS fragments before debugging them.
Minify XML for fixtures or embedded configuration values.
Quickly identify mismatched tags in copied XML samples.

Good to know

This tool focuses on formatting and structural checks. It does not validate against an XSD schema or fetch external entities.

How to inspect XML

Format the document first, then review opening and closing tags from the outside in. Well-indented XML makes it much easier to spot mismatched nesting in SOAP messages, RSS feeds, and exported configuration.

What this tool checks

The formatter checks whether the markup is structurally parseable in the browser. It is useful for quick review, but it does not replace schema validation, namespace-specific rules, or application-level tests.

Common mistakes

A document can be well-formed and still wrong for the receiving system. Watch for missing namespaces, escaped text that should be CDATA, and character encoding assumptions outside the copied snippet.

Before you rely on the output

Use representative samples and validate the result in the target parser or application before replacing production configuration or data files.
