Plug in creation for Kirby CMS

[Andreas Petersell]

I need help creating a plugin. It creates text files for the file based CMS Kirby. But Kirby CMS expects that each text file is located in a separate directory:

parent-directory/example/example.txt

But the link to example.txt must be only:

parent-directory/example

Which template do I have to change to shorten the linking path? And where can I find it within the DITA-OT? The plugin is based on the xhtml plugin and it is a slighty changed variation of Jarno Elovirta´s plugin net.sourceforge.dita-ot.html

Thanks in advance. Greetings Andreas
