Problem with variable that contains certain characters in replacement side of regex substitution.

JTomb has asked for the wisdom of the Perl Monks concerning the following question:

I have the following:

$puid="fmt/412";
$file_path="C:\Service Record.docx";
[download]

I'm trying to substitute plain text for the variables as in:

$cont=~s/FilePath/\Q$file_path\E/g;
$cont=~s/PUID/\Q$puid\E/g;
[download]

Problem is I end up with:

fmt\/412
and
C\:\\Service\ Record\.docx

From what I can tell, Perl wants to add escape characters, or something along those lines.

Is there a way to get around this?
Thanks!

Joe

Perl wants to add escape characters No, Perl does not want to, you tell it to do so by using `\Q`. `\Q` is usually only needed in the pattern, not in the replacement part of the substitution. Remove it and Perl will behave. BTW, backslash must be backslashed in double quotes. لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l] [select]

Thanks! That did it. Not sure why I thought to use \Q the way I did. Joe	[reply]
