Re: Speed up processing a certain string

If you compile one regular expression at the beginning all the matches should be quite fast. I did not make a speed test, but I can give you a short example I just crafted. Feel free to fix any matching errors because I do not know the correct syntax.
And if you want to try out some regular expressions try this tool and switch to the Python language: https://regex101.com/
