In the following
XML::Simple program,
XMLin produces an empty hashref for the key
groups.
I'm curious (after searching the FAQ and this site) how to force such an element to an empty string:
use XML::Simple;
my $xml=<<'EOXML';
<config logdir="/var/log/foo/" debugfile="/tmp/foo.debug">
<groups></groups>
<age>18</age>
<weight>220</weight>
</config>
EOXML
my $xs = XML::Simple->new;
my $ref = $xs->XMLin($xml);
use Data::Dumper;
warn Dumper($ref);
transcript
[tbrannon@devel tmp]$ perl xml-simple.pl
$VAR1 = {
'debugfile' => '/tmp/foo.debug',
'weight' => '220',
'groups' => {}, #### <---- want empty string here!
'age' => '18',
'logdir' => '/var/log/foo/'
};
