Frequently Asked Questions

What makes this different from the XML Viewer?

The XML Editor is a unified workspace for actively creating and modifying XML. It combines editing, real-time validation, formatting, search/replace, and document analysis in a single interface. The Viewer is read-only and focused on exploration.

Does the editor validate XML in real time?

Yes. As you type, the editor continuously checks for well-formedness issues and displays errors with line numbers and descriptions directly above the editing area.

Can I format or minify XML inside the editor?

Yes. Use the Format button to pretty-print with your chosen indentation style (2 spaces, 4 spaces, or tabs), or the Minify button to compress the XML to a single line.

Does the search support regular expressions?

Yes. The search field accepts JavaScript-style regular expressions. Replace All applies the regex globally across the document.

Is my XML data stored or uploaded?

No. All editing, validation, formatting, and analysis happen entirely in your browser. Nothing is sent to any server.
