EXCERPT:
FlashGrab: an Anki addon for pulling flashcard data (one-way sync) from XML. Optimized for LIFT XML (from WeSay or FLEx).
Do you have data that you would like to drill yourself on in a flashcard program? Is that data available
as an XML file? If so, you may be able to use Anki and this addon to pull your data in. (This tool has
only been tested with LIFT input files, but it is a generic solution that could work with other XML
formats too.)
Assumption: you want to do your editing elsewhere and simply pull the latest data into Anki; or, you
will be importing your data one time and editing only in Anki after that.
