Make Notepad++ auto close HTML/XML tags after the slash(the Dreamweaver way)

I've been looking for a Notepad++ plugin that can close HTML/XML tags after a slash just like the way Dreamweaver does for a long time.
The only things I could find(TextFX, XML Tools etc.) close the tags right after ">" is typed in, which was not what I wanted.
A couple days ago I found a plugin called Automation Scripts. It allows me to write scripts in C#, so I don't have to spend time learning how to write Notepad++ plugins.
So here you go:

//npp_shortcut Ctrl+Shift+Z

//Automation Scripts plugin needs to be installed for this to work
