XML Formatter and Validator

XML (eXtensible Markup Language) is a markup language that defines rules for encoding documents in a format that is both human-readable and machine-readable. It is widely used for data exchange between systems, configuration files, and structured data storage.

Basic XML Syntax

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <element attribute="value">
    Text content
  </element>
  <selfClosing />
</root>

XML vs JSON

• XML uses opening and closing tags, JSON uses braces and brackets
• XML supports attributes on elements, JSON uses only key-value pairs
• XML is more verbose, JSON is more compact
• XML has native namespace support, JSON does not

Usage Tips

When working with XML, always validate the document before processing it. Use formatting tools to improve readability during development. For modern APIs, consider using JSON, but keep XML for legacy integrations and configuration files.
