Using Python to connect to an XML ?

[Gribouillis]

I understand that KMyMoney can save its data in a SQLite 3 database. You could then export the database tables to spreadsheets by various means, this is a standard task.

Also, XML is not something you connect to. It is only a general data format that you can read and write. You can read an XML file using modules lxml or beautifulsoup.
