This is the further development of the script found here. First we transformed the history of the linked wiki page into the history of a source code repository and afterwards continued the development by adapting the script to the current versions of the applications.
The result is a Python3 script which takes a TikiWiki exported .tar-file, and a TikiWiki URL as input and delivers an XML-file to import into a MediaWiki instance, or an XWiki instance using the Filter Streams Converter Application and following the procedure to import MediaWiki content as described here.
First you should create a virtual environment based on a recent Python version (the provided requirements.txt file was compiled for Python 3.9 using pip-tools).
To accomplish the environment setup just execute the following in bash oder Windows command prompt:
$ python -m venv tiki2mediawiki_conversion_venv
$ source tiki2mediawiki_conversion_venv/bin/activate
(tiki2mediawiki_conversion_venv) $ pip install --upgrade pip setuptools pip-tools
Collecting pip
