Another question since I hit another snag on this, hopefully it's the last =)
Sample -->
$s2 = "c:\ise\conf\ise_eif_lvc.config";
$s1 = <STDIN>; # This could be from command line or reading from a file
# But the input will be the following --
#<add key="instrumentationConfig" value="c:\ise\conf\ise_eif_lvc.config" />
if( $s1 =~ m/\Q$s2\E/i ){
print "matched\n";
}
Somehow this would work, and seems to be the double-quote in the input that's
causing the issue. I've tried the quotemeta on $s1, but that didn't help.
Although if I put the actual string into $s1 and use \ to escape the ", then it
would work. I thought quotemeta does just that.
Again, many thx in advance.
Han

To match non-alphanumeric characters in a string, you need to quotemeta
it.
if( $s1 =~ m/\Q$s2\E/i ){
# ...
Or
my $s2 = quotemeta( $s1 );
if( $s1 =~ m/$s2/i ){
# ...
See:

The key to success is being too stupid to realize you can fail.
