Important! Again, I reiterate, because this is important!
How do you pretty print indent and format XML? Yeah, I remember I
searched for this, but then I dropped it thinking it was just too
obvious. But then I realize I had to search for it again. So, I will
take a note of it too. It’s easy to do from a GNU/Linux command line
if you have libxml tools installed.
xmllint --format file.xml
