OK, first steps are:
1. Install 7zip and Notepad++ which you can find online.
2. Open the .doc file in Word and do a SaveAs to change its format to .docx. Doc file format is very old and won't work with this method.
3. Make sure Notepad++ is set as your default application to edit .xml files. Do this by creating a text file on your machine and changing its file extension to .xml. If double clicking it opens it in Notepad++ then you are good to go. If not, right click on the file and choose Open with... to select Notepad++. Make sure you check the box that says "Always use this app to open..."

I'll post the rest of the instructions later.
