Why Convert XML Data To Hash Structure Using XML::SAX?

Instead of using XML::Simple? The structure, generated by XML::Simple, is not consistent since it recognizes an empty tag as empty hash structure, instead of null string.

1. Consider this XML data:
   

   <Order>
     <Number>01234</Number>
     <Status />
   </Order>

2. Using XML::Simple produces:

   $VAR1 = {
     'Order' => {
       'Status' => {},
       'Number' => '01234'
     }
   };

3. Utilizing XML::SAX, we could insert a null string instead of an empty hash structure:

   $VAR1 = {
     'Order' => {
       'Status' => '',
       'Number' => '01234'
     }
   };

Remember: it is simpler to assume that all end of hash structure branch is represented by ref($hash) eq "".
