I've been tring to find a way to detect "partial/wobbly" regexp matches i.e. given a string of charaters, return all matches to a regexp, with maximum of 2 failures/mismatches.
$str = "PolarBear";
$str =~ /polarbear/; #returns 2, and/or [0,5] for positions
$str =~ /Polerbear/; #returns 2, and/or [3,5] for positions
$str =~ /Polarbeer/; #returns 3, and/or [5,7] for positions
How would I go about, or is it even possible, to return the number of times the reg-exp fails and/or list the positions in the string.
P.S. Ive looked at node id=74651, but is this what I am looking for.... is it stable?
