how to install sublime text indent xml in sublime 3

None of the above answers worked for me as they appeared to be missing a crucial 'step' to the process (step 2 below). This is how I got it to install for me in Windows using Sublime Text 3:

1. Install Package Control (Tools > Install Package Control...)
2. Open Package Control (Ctrl+Shift+P) and type 'Package Control: Install Package' and then press Enter.
3. Sublime will attempt to load any custom repositories then offer a list of packages available.
4. At this point, I was able to successfully search for 'indent xml' and have it appear in the list and install by pressing Enter with it selected.

If you are using Mac, go to the menu as follows:

Sublime Text --> Preferences --> Package Control --> Install Package

When the list box opens, type indent xml ( or a different package indentx ).

Once the package is installed, Command+Shift+P

Then choose indent xml to automatically format your file.

The most error free way, is to

1. Install the Package Control First
2. Ctl + shift + P then type Install Package and press Enter
3. Type Indent XML and press Enter

To Use:

1. Open the XML file that you need to reformat
2. Ctl + shift + P then type Indent XML
3. Press Enter

Your Document will then update.
