> strings
Description: I have 2 strings which should be identical:
$PDBline;
$XMLline;
and I test for this normally:
if ($PDBline eq $XMLline){etc...}
However in the event that they dont match I want to do a percentage comparison where I match each word in $PDBline against the words in $XMLline.
So say I want a 75 % similarity between the 2 strings...
my $threshold = 0.75;
my $counter = 0;
foreach my $word ( split ' ', $PDBline ) {
$counter++ if $XMLline =~ /$word/;
}
Does this seem right or is there an easier way to do this??
