Can someone please guide me through this file parsing example? I am trying to search for the last occurence of a particular line in a file. Then skip three lines. Next, I want to create a hash starting at the fourth line and ending when a blank line is found. An example of the test is this. Here is an example of the file and my code so far. Thanks!
