What is one of the primary advantages of using XML?

One of the primary advantages of using XML is that it provides a flexible way to structure data. XML, which stands for eXtensible Markup Language, allows developers to create their own markup languages tailored to the needs of their applications, making it adaptable for various data types and structures. This flexibility enables easy representation of complex data relationships and hierarchies, facilitating data sharing and transmission between different systems, platforms, or applications.

Because XML is text-based and self-descriptive, it allows both humans and machines to read and understand the data more easily, promoting interoperability across diverse systems. This is particularly beneficial in web services, configuration files, and many types of data storage and exchanges where varied data structures are required. The extensible nature of XML ensures that as new requirements emerge, developers can modify the schema or introduce new elements without breaking compatibility with existing systems.
