I want to be able to generate ParseTree and dump it into xml like in Spirit Classic. In the Classic we call pt_parse() which return tree_parse_info and we can dump it into XML easily using tree_to_xml().
Do we have the same functionality in Spirit 2.1?
Spirit 2.1 does not have any special API functions for AST generation. It's all intrinsic. You really should look at the examples (for instance mini_xml[1-3].cpp) and read the docs (http://tinyurl.com/ojalum). The introduction there guides you nicely through how it's done. As for XML generation, we don't have this in Spirit 2.1 at all. Every parser may now generate a structurally different PT/AST, so having a common dump function is not feasible. You'll have to craft your own (the examples show how you may want to do that as well). Regards Hartmut ------------------- Meet me at BoostCon http://boostcon.com
