XML Validation and Formatting for Web Developers

Extensible Markup Language (XML) is used extensively in enterprise software, legacy SOAP web services, Android application manifests (`AndroidManifest.xml`), RSS news syndication feeds, and search engine XML sitemaps. Minified XML strings without indentation or line breaks are nearly impossible to debug by hand.

Native DOM Validation

Detect unclosed tags, mismatched root nodes, and attribute quote syntax errors instantly before deploying.

Clean Indentation

Automatically formats opening tags, self-closing tags, namespaces, and inner text on clean indented lines.

100% Client-Side

Enterprise XML schemas, confidential XML payloads, and customer records remain strictly private on your computer.

Frequently Asked Questions

Yes. You can paste any valid XML document including sitemap.xml, Android layout XML, Maven pom.xml, SVG vector files, or SOAP payloads.

Unlike HTML, XML is strictly typed. All opening tags must have matching closing tags (or be self-closing with />), attribute values must always be quoted (key="value"), and the document must have exactly one root element.
