Hello,
 
I'd like to subclass XML::LibXML::Document in order to assist with creation
of  XML documents (I want to ease XML creation and have all the facilities
of a DOM).  Additionally, I'd like my subclass of XML::LibXML::Document to
be an "event notifiier".  So when nodes are added or modified, e.g. - the
subclass' state has changed,  I'd like it to be able to fire off events to
listeners.
 
I can subclass Document just fine... The problem I am having is that I can
not work with XML::LibXML::Document since it seems to be a scalar ref and
not a hash ref.  When I try to add additional properties to it, it fails
with (Not a HASH reference...).  Is there any way around this?  I'd like to
subclass rather than wrap a Document.
 
My constructor goes something like:
 
Our @ISA = qw{XML::LibXML::Document);
 
Sub new{
            My $class = shift;
            My $self = $class-> SUPER::new('1.0','UTF8');     
Bless $self, $class;
 
$self-> {'Listeners'} = []; # fails!
Return $self,
}
 
Thanks!
 
Al
