I have the following code to find a quote in a string and replace it
with a slashquote.

ie " goes to \"

How do I get it to do more than one substitution in the string.


$_ = $$Rules{$yes}{rule_desc};
s/"/\\"/;
$$Rules{$yes}{rule_desc} = $_;

newbie...

The /g modifier, for "global".

Let's clean that up a little. We don't need $_ here.

$$Rules{$yes}{rule_desc} =~ s/"/\\"/g;

How's that?

By using the /g modifier.

No. Don't _ever_ try to set $_ yourself, unless you _really_ have to
(which you don't in this case).

These three lines could easily have been shortened down to only one;

$$Rules{$yes}{rule_desc} =~ s/"/\\"/g;

However: Why do you need to quote the " characters?

The /g modifier worked thanks all. I needed to take the quotes in the
file and backslash them so the file could be read into one of our tools
without a problem. Thanks for the short version too. I never thought
of it that way.

Newbie..

Put a g before the second semicolon above.
