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

1 Nov 2009

      What is Spirit.Qi is that a Spirit new version?

I don't see any information about it in boost.org page.

Do you have a link that you can share with me?

Thanks

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 ?
Probably because of the rule indirection. You *really* should be
using Spirit.QI, not Spirit.Classic like you are, it has no such
problems.
Also, there is a Spirit mailing list, you will get much faster responses there.
