Here are the Google trends that show XML’s declining popularity: Today’s popular choices are JSON and YAML. The newer servers, such as NodeJS, do not have XML capabilities by default. Have you worked with those bulky web.xml files? XML configuration files have been used by many different application servers, such as Apache Tomcat and Jetty.

XML is no longer a viable choice to build websites. However, modern web applications are written by JavaScript framework/libraries, such as React, Angular, and Vue.
