XML vs JSON: Which is Better for APIs?

What are the main differences between XML and JSON for APIs?

XML is a markup language that uses tags to define data, while JSON is a lightweight data interchange format that uses key-value pairs. JSON is generally easier to read and write, making it more popular for APIs.

Which one is more efficient in terms of data size?

JSON is typically more compact than XML, resulting in smaller data sizes. This can lead to faster transmission over networks.

Are there any specific use cases where XML is preferred over JSON?

Yes, XML is often preferred in scenarios where document structure and metadata are important, such as in SOAP web services or when dealing with complex data hierarchies.

Can you give me an example of how data is structured in both formats?

Sure! In JSON, a simple object might look like this: {"name": "John", "age": 30}. In XML, it would be: <person><name>John</name><age>30</age></person>.
