XML Schema is a W3C standard that defines the structure, content, and constraints of XML documents. It serves as a blueprint for data validation and ensures consistency across different systems. 📄

Key Features

  • Data Validation: Ensures XML documents conform to predefined rules.
  • Type Definitions: Supports complex data types (e.g., string, integer, date).
  • Namespace Support: Enables proper handling of XML namespaces.
  • Extensibility: Allows customization for specific use cases.

Use Cases

  • Data Interchange: Standardize data formats between applications.
  • API Documentation: Define expected request/response structures.
  • Configuration Files: Validate settings in XML-based configs.

Example

<schema xmlns="http://www.w3.org/2001/XMLSchema">
  <element name="book">
    <complexType>
      <sequence>
        <element name="title" type="string"/>
        <element name="author" type="string"/>
      </sequence>
    </complexType>
  </element>
</schema>
