Fixing confused bayesian matching data?

Philip:

Sorry for the delay in responding to your message. I waited until I had 
something useful posted where you could see it.

I was in exactly your situation back in February.

This is probably because I like to rejig my accounts from time to time as I continue to figure out what works best for me.  Looking through the ".gnucash" file, I see lots of slot entries with account names that don't exist any more....

My solution? XSLT processing <https://en.wikipedia.org/wiki/XSLT>. 
GnuCash files can be saved as XML format data, and XSLT is a tool for 
modifying XML data in a controlled, reliable way. I wrote a set of XSLT 
filters which:

 1. lists the Bayes mapping data for each account in a gnucash XML file;
 2. resets the import mapping, by deleting all the Bayes mapping data
    for every account in a gnucash XML file; and
 3. prunes the import mapping data for certain target accounts in a
    gnucash XML file.

A rather brief explanation of the situation and the GnuCash file format, 
with listings of all the XSLT filters, is in my freshly-written blog 
post, /Resetting GnuCash’s import transaction matching/

Take a look. I hope it's helpful.
