Frequently Asked Questions About XML Formatter

What makes XML well formed?

One root element, matched and case-consistent tags, quoted attribute values and escaped special characters such as & and <.

Does it check my XSD or DTD?

The browser parser checks well-formedness only. Schema validation needs the schema processor in your build, so treat a clean result here as a syntax pass, not a contract check.

What is XML?

Extensible Markup Language stores hierarchical data with custom tags, common in configs, RSS, and legacy integrations.

Why format XML?

Feeds and SOAP payloads are hard to read without indentation. The XML Formatter aligns opening and closing tags for easier navigation.

Common rules:

Every element needs a closing tag or self-close syntax; attributes must be quoted; one root element wraps the document.
