Hello Monks,

I have a small problem that I can't seem to solve. I need to find duplicate text within a paragraph. Let's say my text looks like this:

"The cat jumped over the dog. Smart cat! He jumped over the dog. The cat jumped over the dog."

I don't need to find all 3 repetitions of the word cat. However, I need to find the longest repeated sentence: 'The cat jumped over the dog'.

I was thinking of a lookahead, and tried something like 

 
m/([\w\s\.]?){?=$1)/g;

[download]

which kinda fails miserably.

Any help much appreciated!
