how to rename a file based on XMP values?

I have a files with multiple IDs in the keyword field of information tab.

I want to rename the file with the values I have in the fields.

For example, with file1.psd:

in keywords I have: 36607675; 36607675; 20999012; 20999013;

I want to have 5 files at the end :

36607675.psd

36607675.psd

20999012.psd

20999013.psd

file1.psd

I tried to create a script by using ScriptingListener plugin, but it didn't works and the code generated is a little be hard to understand. He doesn't take care of the metadata of the other files...

After that i tried to find some tutorials but evryone try to add XMP data, not retrieve it for use them.

Thanks in advance for your help and best regards
