📖 What is XML Formatter?
XML Formatter takes messy, minified or single-line XML and reformats it with proper indentation and line breaks. It also validates XML syntax and reports parsing errors. Use it to clean up XML from SOAP responses, config files, RSS feeds or any source where formatting was stripped. Everything runs in your browser.
💡 Example
Input
<root><item id="1"><name>Test</name></item></root>
Output
<root>
<item id="1">
<name>Test</name>
</item>
</root>
🛠️ Common Use Cases
- Formatting SOAP/XML API responses for readability
- Beautifying XML configuration files
- Validating XML syntax before processing
- Cleaning up RSS/Atom feed XML
- Formatting XML for documentation or code review
📝 XML vs JSON
- XML supports attributes, namespaces and mixed content — JSON does not
- JSON is simpler and lighter for data exchange
- XML is still dominant in SOAP, RSS, SVG, Office documents and enterprise integrations
- Use the format your API or system requires
⚠️ Common Mistakes
- Unclosed tags — every opening tag needs a closing tag or self-closing syntax
- Special characters in content — use < > & for < > & inside text content
- Encoding declaration mismatch — the XML declaration encoding must match the actual file encoding
