Parse API with custom text format output

I have a web API which outputs a list of rain precipication in a custom text format:

https://gpsgadget.buienradar.nl/data/raintext?lat=50&lon=3

The result of the API call is something like this:

000|23:40
000|23:45
000|23:50
000|23:55
000|00:00
000|00:05
000|00:10
000|00:15
000|00:20

I want to show this on a dashboard as a bar chart (multiple values). I tried both REST sensor and command_line sensor to parse the data, but with no luck. Can anyone give me a hint where to look for examples or pointers of a solution?
