text

问题 I want to know if there is a way to read a text file that lets say has content like so: Store - 001P Owner - Greg Price - 45000 Employees - 30 Store - 002 Owner- Jen Price - 34400 Now lets say I only want to work with the store information in the block where the store number contains a P. Is there a way to read the text file to check for the P after the delimiter, and then skip to the next instance of "store" in the text file? I tried to find which function is best as in different languages
