[Boost-users] [Spirit] xml parse tree printing double leaf node

31 Oct 2009

      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

HT
