Working with XML Documents

XML is still widely used in SOAP APIs, RSS feeds, SVG files, and enterprise integrations. Properly indented XML is much easier to debug and review. Common issues include unclosed tags, mismatched nesting, and unescaped special characters (&, <, >). This formatter catches structural errors and shows exactly where the problem is in your markup.

When to Use the XML Formatter

Use this formatter whenever you encounter minified or poorly indented XML that is difficult to read. This commonly happens with SOAP API responses, auto-generated XML configuration files, SVG files exported from design tools, and XML database dumps. Proper formatting makes debugging and code review significantly faster.

Common Use Cases

• ·Debugging SOAP API responses by formatting the raw XML for readability → JSON Formatter & Validator
• ·Formatting SVG files exported from Figma or Illustrator for manual editing
• ·Prettifying XML configuration files for web servers (Apache, IIS) and application servers
• ·Making RSS/Atom feed XML readable for troubleshooting syndication issues → YAML ↔ JSON Converter

Expert Tips

• ✻Use 2-space indentation for XML that will be stored in version control - it reduces diff noise compared to 4-space or tab indentation
• ✻If formatting fails, the error message points to the first parsing error - fix that issue first as subsequent errors are often cascading
• ✻For XML with CDATA sections, the formatter preserves content inside CDATA blocks exactly as-is
