Does Google use XML?

I'm curious to know if the tech giant, Google, incorporates XML in its operations. XML, or Extensible Markup Language, is a widely-used format for encoding data. It's versatile and can be applied in various settings, from web development to software integration. Does Google leverage this powerful tool to streamline its processes, facilitate data exchange, or enhance the functionality of its services? I'm eager to learn more about the role of XML, if any, within the intricate workings of Google.
