[GNC] New to XML; recreating some unsaved work

[Eric H. Bowen]

When I first started using Gnucash I set up my data file with sqlite. 
Lately, though, every time I've tried to open it the database has been 
corrupted. I eventually went back to an earlier saved version and 
reconstructed my data, then started saving it in .XML format, with 
autosave turned on.

However, that doesn't apparently save to the data file. I was working on 
my books last night, but the computer restarted due to an update and the 
master file was not saved. So now I have the master file time-stamped at 
7 am yesterday morning, and about 25 xml text files from the automatic 
saves as I worked. How do I roll those into the master file and update 
it without having to re-create the complex invoice I was working on?
