Dear community, I have a problem when I try to count the items in a hash variable which was created by XML::Simple from a xml file.

My xml looks like:
<?xml version="1.0" encoding="UTF-8"?>
<config>
    <log>
        <destination>e1@mail.de</destination>
        <destination>e2@mail.de</destination>
        <destination>e3@mail.de</destination>
    </log>
    <item>
        <id>0</id>
        <filename>file1</filename>
        <extension>txt</extension>
    </item>
    <item>
        <id>1</id>
        <filename>file2</filename>
        <extension>txt</extension>
    </item>
</config>

if i try to count the <destination> items with scalar (keys $config->{log}->{destination}); AND there are more then 1 destinations, then it works fine. But if I reduce it in the xml to just one email address it throws an error:
Type of argument to keys on reference must be unblessed hashref or arr
+ayref at test.pl line 13.

The second problem which I have is to count the <item> nodes. If there are more then one nodes it works fine, like by <destination>. But if there is just one <item> node, it counts the nodes in this <item>. In my case it is 3 (<id>,<filename>,<extension>).

The way I translated my xml file in Hash is:
use XML::Simple qw(:strict);
$config = XMLin('config.xml', KeyAttr => { server => 'name' }, ForceAr
+ray => [ 'server', 'address' ]);

I would be glad, if someone could help me, because I didn't find anything while googling...

thanks a lot!
Dimitri

p.s
by some reason the word array splits here automatically in "ar+
ray"
