XML is an abbreviation for Extensible Markup Language. It is a markup language that allows us to define and store data in a way that can be shared. Additionally, it supports the exchange of information between computer systems, such as websites, databases, and third-party applications.
Similarly to HTML, in XML we also write tags, but here we define them according to our own needs. XML allows data to be transmitted along with its description, preventing the loss of data integrity. Computer programs, such as search engines, can sort and categorize XML files more efficiently and accurately than other types of documents. Based on XML tags, search engines can precisely categorize content for relevant search results. Thus, XML helps computers interpret natural language more effectively.
