How do I save a pw-protected MS word doc as an xml file?

[guru123]

I have tried "renaming" the document with a ".xml" extension, but it still appears with a word document icon on my desktop, and when I right click it, it still says it is a word document. What the file ends up saying is "FILENAME.xml.doc" (no quotation marks). I read online that other people have been able to change the file type of a word doc simply by renaming it. How do I save a password-protected MS word doc as an xml file?I run MS Office 2010 if that is of any use. I found a USB drive from when I was still in my middle school years, and it is like a tiny time capsule (sort of). I put a password on a document but can't remember what it was.I would appreciate any help!
