[GNC] How to Copy Transactions From .xml.gnucash to .gnucash File

[Glenn Bordonada]

I saved my .gnucash file as .xml.gnucash file.
In my next data entry session, I forgot about this and entered some transactions. These were entered into the .xml.gnucash file.
Now I want to go back to using my old .gnucash file. How do I recover the transactions I entered into .xml.gnucash file.
Is there a way of saving the xml.gnucash file as .gnucash file?
