Parsing ICS to populate a calender (here: FullCalender.io)

The CMS Questions
1

Hi

I would like to display a calender (using FullCalendar.io). The calender itself works: https://www.niehaus-ol.de/allgemeines/kalender

My question is about parsing a .ics-File. The calender is going to be readonly. It will display events that are stored in a .ics-file. The file itself is maintained in Outlook and exported ~once a week.

Now my problem is about the parsing. I general it I need to do basically this in pseudocode)

calenderdata = file.open('calender.ics')
for event in calenderdata:
    create_event(...)

But how do I do that? Has anyone here ever done this? I could write a simple parser myself, but there has to be a simple library for this… I just cannot find it…

The fileformat (this is real data) looks like this:

There are several solutions like iCalCreator: Create schedule calendars in iCal format - PHP Classes.

But perhaps somebody here has a good solution for such a simple parsing-‘problem’…?

Just an update, in case somebody runs into this problem him/herself:

I created a PHP-Script that rewrites ICS to JSON. This JSON can be read in by Fullcalender.io. So solved outside of Kirby.
