FoLia-2text: extracting original text from a correction

[kosloot]

Given this folia (also attached correctie.xml.txt)
FoLiA-2text can extract the corrected text: één.. But there is no way to extract the original text.

The naive FoLiA-2text --class original doesn't work.
So how to do this?
@proycon same question for folia2txtfrom FoliaPY

Yes, class original doesn't work (that used to be something in an early FoLiA version). The example is valid and correct, both have the current class. There is a solution for retrieving this, but I'm not sure to what extent it's also implemented in libfolia. For text() and textcontent() I use the correctionhandling parameter to choose which path to follow, the value can be either CURRENT, ORIGINAL or EITHER. A value of "CURRENT" follows the normal authoritative path (i.e <new> or <current>, note that despite the name this does not relate to text classes at all anymore) and "ORIGINAL" follows the original path.

folia2txt doesn't provide an interface to this currently, foliacorrect does.

I would very much like to see this implemented in folia2txt. @proycon Should I add an issue ?

[proycon]

Yes, that sounds like a good idea yes. (may take a bit before I get to it though)
