Slightly Off-Topic: Script to correct date in MetaData

[Netbug 26]

I've posted a few times about incorrect data stored in the metadata of much of my collection. A large portion is showing added in 2014 and 2015.

 

I've been going through them one-by-one through the MB3 web interface, but it is tedious as hell.

 

I was wondering if anyone knew how to, and would be willing to (or to point me in the right direction to learn how to), create a simple script to read the information contained the in the metadata and replace the date line.

 

The pseudo-code would be

 

open metadata file

if <Added>26/10/2014 12:00:00 AM</Added> is greater than 2013

  then replace with

  <Added>01/01/2013 12:00:00 AM</Added>

  save

  check the next file

else

  check the next file

 

I have no idea how to code. Anybody willing to give this a shot?
