Dear Brethren of the Order,

My module takes a chunk of three level simple XML from XML::Simple with $xml=XMLin($xmlstream); and converts the resulting array/hash into a variety of formats.

The code below reads in and stores the element names and their contents. This means that no prior knowledge of the element names is necessary, so that the module can read any three level simple XML file. 
sub init() {
 my ($self)=@_;
 my $source=$self->matrix;
 foreach my $node(keys (%$source)) {
      my $elem=$source->{$node};
      my $count=0;
      foreach my $attr (@$elem) {              ##### line 60
         $self->print.="\n\n$node $count\n\n";
         if ($count<1) {$self->nodename=$node;}
         foreach my $subnode(keys(%$attr)) {
                 $self->print.=$subnode."\t".$attr->{$subnode}."\n";
         }
         $count++;
      }
 }
}

It worked beautifully until I started to test the boundaries. With huge chunks of XML it works fine, with smallish ones also, for example: 
<root>
<car>
<make>audi</make>
</car>
<car>
<make>sbarro</make>
</car>
</root>

However, if there is only one element, such as: 
<root>
<car>
<make>audi</make>
</car>
</root>

Then I get this error: Not an ARRAY reference at transForm.pm line 60.

I am starting to feel a little bit out of my depth here... Can anybody help me?

Thank you, O holy ones
