Might be, but I am not generting XML, but HTML... And there are many ways to write code that looks visually the same, and yet is wildly different. More so for, lets say SVG. Sometimes I resort to "soft" tests, like looking if I find certain strings in the output, like for "[ Bonn ] -> [ Berlin ]", you expect "Bonn" and "Berlin" in there somewhere...
