Access password-protected document

I forgot a document’s password but need to open it. I read something about using an xml copy editor to do disable a doc’s protection. Can anyone provide steps to do this using this editor or any other method? I’m good at following directions but not very technical. Thanks in advance.

That’s next to impossible.

@Lupp has posted a macro which could help but don’t count too much on it. LO password protection is a really good one.
