perlquestion sandy1028 Hi, I have to read the file and if I find the characters like &ldquo,&rdquo,&rsquo I have to replace it with some characters. <code> $data =~ s/&ldquo;/&#8220;/g; # change the lines $data =~ s/&rdquo;/&#8221;/gi; $data =~ s/&rsquo;/&#8217;/gi; </code> But this is not replaced in the file when it occurs. How to do this
