Finding a Block of Text in a Larger Block of Textby Anonymous Monk |

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:
I have multiple text lines that constitute a block of text such as two examples shown below. The second block of text begins with the 2nd "ADD RULE" statement:
My objective is to take a block of text that constitutes a single "ADD RULE" statement, with all it's associated components, and search a larger file containing literally thousands of similar ADD RULE statements and identify duplicates of two types. 1) An exact duplicate: all components of the ADD RULE statement match exactly, or 2) A functional duplicate: The RULESETNAME, VARIABLE, OPERATOR, and VALUE, are an exact match. I have written some code that can grab a block of text that constitutes one ADD RULE statement. I can't figure out how to compare that block of text with the larger file and produce a list of exact or functional duplicates. Any thoughts would be appreciated.
