Sorry, but there is no formatter for 'xml'-files installed.
Sometimes I question my sanity.
I’ve used Visual Studio Code (VS Code) since it was revealed at Build. One of its many useful features is the ability to format documents in a human readable form. This includes XML.
Or so I thought.
Sorry, but there is no formatter for ‘xml’-files installed.

So my VS Code just lost it’s ability to format XML. Good for it, but as I create Enterprise Software (tm) I need my JSON++ formatted dammit!
Luckily, the thriving extension community of VS Code had at least one XML formatter ready for my use.

I used vs-code-xml-format
and it formats my XML perfectly.
