XML Formatter & Validator

This tool formats XML documents for readability by adding proper indentation and placing each element on its own line. It validates your XML using the browser's built-in DOMParser before formatting.

Validation: Checks for well-formedness — properly nested tags, matching open/close tags, valid attribute syntax, and correct use of special characters. Reports the first error found.

Minify: Removes all unnecessary whitespace between tags and strips comments, producing compact single-line XML. Useful for reducing payload size in APIs and configuration files.

Supported features: XML declarations (<?xml?>), processing instructions, comments (<!-- -->), CDATA sections (<![CDATA[]]>), DOCTYPE declarations, namespaced elements, and self-closing tags.
