What is XML?
XML (eXtensible Markup Language) is a markup language for storing and transporting structured data. Unlike HTML, XML tags are not predefined — you define your own tags to describe data. XML is used in configuration files (Maven, Android, .NET), data interchange (SOAP, RSS, SVG), and document formats (DOCX, XLSX, ODT).
Well-formed XML requires every opening tag to have a closing tag, proper nesting, case-sensitive tag names, and a single root element. This formatter validates XML structure and reports errors with the position of the first syntax problem.
Common Use Cases
- API debugging — format SOAP responses and XML API payloads for readability.
- Configuration files — beautify pom.xml, AndroidManifest.xml, web.config, .csproj files.
- SVG editing — format SVG markup to inspect and modify vector graphics code.
- RSS/Atom feeds — validate and format syndication feed XML.
