[Spirit] xml parse tree printing double leaf node
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.
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 HT

It has been available in the trunk for near a year (and now on the release branch for a few weeks now) if you want to use it now like we are.
