I have Notepad++ and I got some XML code which is very long. When I pasted it in Notepad++ there was a long line of code (difficult to read and work with).
You need to install the XML tool from the Plugins menu item → Plugins Admin... → Plugins Admin dialog appears and then scroll to bottom of available plugins and check the XML tools, install it and then Ctrl + Alt + Shift + B OR the option for XML Tool above shows up.
