I'm afraid I'm missunderstood.
The thing is: I have text in a variable. This text comes from a calender. It is the title of a calander event. It changes everyday and could be any text. Actually it is always the Name of one of many Theater productions.
I search for this variable in a .txt file, that holds a list, in wich this production names and some additional information to it appear several times. I'm doing this, to look if the perfomance took place in the past and if yes get the additional Information, to Do things with it.
This is what i do since in the meantime about 10 years.
Now the problem is, if the text has slashes in it, like in "Bal BALANCHINE/NEUMEIER/ROBBINS" or "Bal TÄNZER/BILDER/SINFONIEN" or like already mentioned "Bal THOSS/WHEELDON/ROBBINS", it's not found.
As far as I know from the guidelines for variables in Tasker, there are no restrictions that would prohibit the use of expressions like the ones above.
Thanks again for help and information
