How do I format XML online?

Paste your XML into the XML Formatter tool. It adds proper indentation, line breaks, and validates the syntax. Works with any valid XML including SVG, RSS, SOAP, and Android layouts.

Is XML still used in 2026?

Yes. XML remains essential for RSS/Atom feeds, SOAP web services, SVG graphics, Android UI layouts, Microsoft Office file formats (.docx is XML), and enterprise data exchange. JSON has replaced it for most APIs, but XML is far from obsolete.

What is the difference between XML and HTML?

XML is strict — every tag must be closed, attribute values must be quoted, and tag names are case-sensitive. HTML is forgiving and has predefined elements. XML allows custom element names; HTML has a fixed vocabulary.
