It used to be that we could specify options when exporting content using basexgui. As the tool no longer allows for this
The feature has not been removed from the GUI. Do you use the Database » Export dialog?
I tried adding indent= false and chop=false to the .basexgui file, but it doesn't seem to help.
The .basexgui file only contains GUI-specific options. You’ll need to add or update the EXPORTER option [1] in .basex.
