Debug XML Sitemaps & Feeds
XML (eXtensible Markup Language) is notorious for being strict. A single missing closing tag or an unescaped ampersand can break your entire WordPress Site, RSS feed, or Sitemap. Our XML Formatter & Validator uses your browser's native DOMParser to strictly validate your code.
Common Validation Errors
- Mismatched Tags: e.g., Opening with
<title>but closing with</name>. - Unescaped Characters: Using
&instead of&in URLs. - Root Element Missing: Valid XML must have exactly one root node.
Key Functions
- Prettify: Fix indentation and nesting for human readability.
- Minify: Remove whitespace to reduce file size (bandwidth saver).
- Validate: Real-time syntax checking using native browser parsing.
