XML (Extensible Markup Language) is a markup language that is used to store, transmit and exchange structured data between different systems. It is a flexible and adaptable format that can be used for a wide variety of purposes.

Some of the main uses of XML include:

Data storage: XML can be used to store data in a structured format, making it easy to read and understand. This makes it a popular choice for storing configuration files and other types of data.

Data exchange: XML is often used to exchange data between different systems, such as between a website and a database, or between different software applications. This is because XML is a widely accepted standard, and many programming languages and platforms have built-in support for it.

Data representation: XML is also used to represent data in a human-readable format, which makes it easy for people to understand and work with. This is useful for creating documents, such as RSS feeds, that can be easily read by both humans and machines.

Data transformation: XML can be used to transform data from one format to another, such as from CSV to XML or vice versa. This is done using XSLT (Extensible Stylesheet Language Transformations) which is a language for transforming XML documents into other formats.

Web Services: XML is also used in web services, which allows different systems to communicate and exchange data over the internet. This is done using technologies such as SOAP (Simple Object Access Protocol) and REST (Representational State Transfer).

XML is widely used in many different fields such as e-commerce, finance, healthcare and many more. It has become an important standard for storing, transmitting and exchanging structured data.

XML is basically used to let know Google-bot know about your pages and posts available on your site so that it become easier for bot to index your web pages in the search engine.
