G'day Rahul Gupta,

Your underlying problem is that the value of $value in $query =~ s/$value/$replace/i is being interpolated: $Id and $name evaluate to zero-length strings so $query =~ s/$value/$replace/i is equivalent to $query =~ s//$replace/i (i.e. no substitutions occur). That was a poor guess on my part; see moritz' explanation instead; the fixes, however, are identical. To fix, use

$query =~ s/\Q$value\E/$replace/i;
