What Is Extensible Markup Language (XML)?

Extensible Markup Language (XML) is a versatile and widely used markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. XML was developed to facilitate the sharing of structured data across different systems, making it a fundamental technology for data interchange on the internet. Its design emphasizes simplicity, generality, and usability across various applications and industries.

In XML, data is represented in a hierarchical structure using tags to define elements and attributes. The language allows users to create their own customized tags, making it "extensible" to accommodate a wide range of data structures. This flexibility has contributed to XML's widespread adoption in various domains, including web development, data storage, configuration files, and communication between different software applications.

One of the key features of XML is its platform and application independence. Since XML is a text-based format, it can be easily read and created by both humans and machines. This interoperability makes XML a preferred choice for data exchange between different systems, ensuring that data remains consistent and structured regardless of the platforms or applications involved in the communication process.
