So, I was able to modify _1 (type of struct ptnode) by using a functor() (e.g. [_val = func(x, _1)] where the function will take a reference of _1 and do some modification to it and return (typeof(_1)&).
Can we also modify _val placeholder on the fly through semantic action? i.e. once _val = _1 executed, then modify the _val object
A semantic action [_val = _1] actually should modify the variable referenced by _val. If it doesn't work for you, please provide a _minimal_ example we could try. And, please move Spirit related discussions to the Spirit mailing list. There you will get more and faster answers. Regards Hartmut ------------------- Meet me at BoostCon http://boostcon.com
