xml technology example

[mark stone]

i have just begun with the xml tutorials.
w3scool tutorial has an example for xml based info displayed with the help or medium of HTML.
what are the other ways that are commonly used by applications, programmers to send/receive/display xml ? sure this list would have programmers who would be working with xml. the w3schools tutorials has an example where they show how xml info is displayed with the help of HTML ie in a web page.
is this (via http) the most commmon way to use xml technology. after all xml does not do any thing, it is just a data structure to layout information. one needs other programs/applications etc to send/receive info that is structured with xml. (typical examples or other technologies extensively using xml...)
also please send me a link to an actual web site that extensively uses xml.
