Despite some notable shortcomings in the contemporary technology landscape, XML is still a powerful language offering key advantages in complex data storage scenarios.
Compared with a popular data interchange format like JSON, for example, XML’s syntax places a greater emphasis on machine readability over human readability, making its error-checking process more efficient. Most importantly, XML is great at storing unique data types with multiple variables, whereas JSON is optimized for relatively simple and concise object storage. XML’s advantages and disadvantages both stem from the fact that it’s not a dedicated data interchange format like JSON at all; rather, it’s a complex markup language (more similar to HTML) with powerful data interchange capabilities.
