dix-mode is an emacs XML editing minor-mode for apertium/lttoolbox dictionaries. This short screencast shows the function dix-xmlise-using-above-elt.
If you have a list of words of the same paradigm, find some entry in your file to use as a template, enter the list below that (one word per line), and run the function to turn it into XML using the above entry as the template. Works with bidix entries too, just use a : to separate the left from the right.
