pattern matching tricky oneby Anonymous Monk |

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:
Hi monks! Suppose you have the following string of letters : $string ='LPSTEOPRTRYERTRETR'; and you want to search for the following pattern inside the string: $pattern= LP[SKTAQEHLDN][TA][GN][EDASTV] =>5/6 By saying 5/6, I mean that you can have one mismatch but still it must return success. If you check the string above, it has L, P, S, T and then E. There is no G in the pattern, but I am ok with it... So, my question is how can you set a threshold in pattern matching above which you will return success... Edited by planetscape - added code tags
