Need Help??

in reply to Getting Error in character class - Regex

Adding a space between two [] worked fine for me. This may be due to the fact that perl tries to parse the second '[]' as extra dimension.

Monks, if wrong please correct me.

use strict;
use warnings;

my %imlre = ('RE1' => ['RE1', 'body', 'measure', 'remove'], 'RE2' => [
+'RE2', 'jcode', '', 'remove']);

my $input = '<front>front matter comes here</front><body>bodymatter co
+mes here</body><back>back matter</back>';

for (keys %imlre)
{

    if ($imlre{$_}->[3] =~ /^remove$/i)
    {
        $input =~ s/<$imlre{$_}->[1] [^>]*>//xg ; #here getting error
        #$input =~ s/<$imlre{$_}->[1]([^>]*)>//g ; #here no error
    }
}

print $input;
