Pretty-print XML with proper nesting, confirm a document is well-formed, or strip whitespace to minify it. Handy for SOAP payloads, RSS feeds, sitemaps and configuration files.
Readable indentation for deeply nested documents
Well-formedness checks with the position of the offending tag
Minify mode strips insignificant whitespace
Frequently asked questions
What does "not well-formed" mean?
It means the document breaks a structural rule: an unclosed tag, mismatched case, or a stray angle bracket. The validator names the position so you can fix it.
Can I format an RSS feed or sitemap with this?
Yes. Both are XML, so paste the feed or sitemap and it formats like any other document.
