When I generating parse tree and dump it using the built-in tree-to-xml function, even from a simple grammar, I wonder why it prints out the leaf node twice.
 
For instance:
 
Parameter = ParameterName >> ParameterValue;
 
The tree it prints it looks more or less like the following (note the repetition of ParameterName and ParameterValue nodes):
 
<Parameter>
     <ParameterName>
            <ParameterName>
                    <value>Foo</value>
            </ParameterName>
     </ParameterName>
     </ParameterValue>
            <ParameterValue>
                    <value>Bar</value>
            </ParameterValue>
     </ParameterValue>
</Parameter>
    
I would be expecting more something like:
 
<Parameter>
     <ParameterName>
           <value>Foo</value>
     </ParameterName>
     </ParameterValue>
           <value>Bar</value>
     </ParameterValue>
</Parameter>
    
 
Is there any directive or secret that I don't know ?
 
Thanks
