Try $frage_text =~ s/\"/\\"/g; I think it will work better this way.

Subject: Escaping quotes in variable content

Hi all,

how can I escape quotes within a variable's content? I use the following
directive to fill an HTML form:




Unfortunately, if $frage_text contains a double quote, the browser will stop
displaying the string at that point.

I tried to escape the quotes in a Perl way

$frage_text =~ s/"/\\"/g;

but that did not help.

 Any suggestion is appreciated.

 Thanks,

 Jan

This wasn't really the question, but... 
If you have to write html within perl, use qq( ) instead of "".
It's a lot easier to read, and much less error prone.

ie,
print qq(
http://www.somewhere.com";>


);

I did use qq{} quoting within the Perl script in the first place. My problem was 
related to quoting within a double-quoted HTML attribute, e.g.

Anyone reading the archive, please don't do this.  escapeHTML or
HTML::Entities should do very well.

RE: Escaping quotes in variable content

[Ash Singh]

This is better, replace the quotes with nothing and then build your input
tag.

#!/usr/bin/perl

use CGI;
use strict;

my $cgi = new CGI; print $cgi->header;
my $query = CGI::new();

my $frage_text= "\"Hello World\"";

$frage_text =~ s/"//g;

print "http://www.somewhere.com\";>\n";
print "   \n";
print "\n";

I hope this helps 
Regards Ash.

Doh. I have been working on the script for several hours now and forgot the
most simple things about HTML.

In HTML characters are 'escaped' by converting them to entities. 
&entityName; Quote marks are "

You probably want to use escapeHTML() from the CGI module.
