The quick and nasty approach is to use string:tokens
of course; something like this if you have a string:
[ string:tokens(Line, "=")
|| Line <- string:tokens(String, "\n") ]
and then getting rid of whitespace, doing
postprocessing and error checking of that (which might
be substantial). It has many limitations, but
sometimes you just need the quick thing.
The main issue is to handle quoting properly for this
approach, which string:tokens does not do; however,
it's probably straightforward to rewrite that function
to take care of the issue for your domain. Hope it
