How It Works & Technical Architecture

The XML Formatter uses the browser’s native DOMParser to parse the input into an XML DOM document, checking for parser errors.

Our formatter traverses the DOM tree recursively, calculating indentation depths, preserving CDATA sections and comments, and aligning attributes.

The output is rendered with syntax highlighting in a high-performance code viewer in your local browser.
