Hello all. I need help with an issue and i cant think of a good way to do this. I need some community help. I have a program that is going to extract specific information out of a text file generated from a pdf. The text file stores one word per line. These
are not very large files, memory efficiency is not the highest priority. But I need to be able to search for a specific match in my text file, and pull the next line, the next two lines, and is some cases, skip a line and pull the following line after the
match is found. I am fairly new at this so any advice would be greatly appreciated...
heres what i have so far:
