regexp substitution problem

[birgit kellner]

use POSIX 'setlocale';
use locale;
use strict;
use warnings;
setlocale( &POSIX::LC_ALL, "de" );
my %rec;
$rec{'content'} = qq|<!-- start query --><input type=hidden name="227" 
value="77"><dl><dt><dd>"Madhyamaka." In: "Buddhismus in Geschichte und 
Gegenwart, Bd. I." Hamburg: Universit�t Hamburg (Weiterbildendes Studium) 
1998, 180-189.</dl><input type=hidden name="230" 
value="77"><dl><dt><dd>"Zum Konzept der Leerheit im BCA." In: "Buddhismus 
in Geschichte und Gegenwart, Bd. III: ZAntidevas "Eintritt in das Leben zur 
Erleuchtung"." Hamburg: Universit�t Hamburg (Weiterbildendes Studium) 1999, 
61-80.</dl><input type=hidden name="229" value="77"><dl><dt><dd>"The 
PrasannapadA: More Manuscripts from Nepal." &nbsp;44 (2000),

Sicht der Leerheit." Tibet und Buddhismus&nbsp;52 (2000), 8-13.</dl><!-- 
end query -->alkjd �slkfdj|;

if ($rec{'content'} =~ /(<!-- start query -->.*?<!-- end query -->)/s) {
        print "YES: there is content with query tags\n";
        my $query = "$1";
        print "QUERY\n---------------------\n$query\n-------------\n";
        $rec{'content'} =~ s/$query/!query!/s;
        print "CONTENT AFTER CHANGE: $rec{'content'}\n";
}

Does anyone know why the substitution in the second line from the bottom is 
not carried out? Does $rec{'content'} contain any illegal characters which 
allow for regexp searching, but prohibit replacing?

Thanks,
