Compare XML and JSON: pros and cons of each format.

XML and JSON are data exchange formats, each with its own advantages and disadvantages.

XML:

• Pros:
  • Supports complex hierarchy and attributes.
  • Well-suited for documents with rich structure.
  • Strictly typed and extensible.
  • Supports schemas (XSD) for validation.
• Cons:
  • More bulky and voluminous compared to JSON.
  • Harder to parse and read manually.

JSON:

• Pros:
  • Lightweight and compact format.
  • Easy for humans to read and write.
  • Parses quickly in many programming languages.
  • Well-suited for web applications and APIs.
• Cons:
  • Fewer capabilities for describing complex structures (no attributes).
  • No built-in support for schemas and validation (though external solutions exist).

In the end, if simplicity and speed are needed — JSON is preferable. If strict structure and validation are important — XML might be better.
