Hello, i need a hint about boost::bind and lambda. Following (reduced) case: class XML_Element { public: const std::string & getName(void); }; class HandleStuff { void handleTransformations( XML_Element * node ); void handleLinks( XML_Element * node ); void handle ( std::list<XML_Element *> * nodes ) { // what i want to do via boost and which will do the job for (std::list< XML_Element *>::iterator it = nodes->begin(); it != nodes->end(); it++) { if ( (*it)->getName() == "Transform" ) handleTransformations(*it); else handleLinks(*it); } // what i tried std::for_each( nodes->begin(); nodes->end(), boost::lambda::if_then_else( boost::bind(&XML_Element::getName, _1) == std::string("Transform"), boost::bind<void>(&HandleStuff::loadTransformations, this, _1), boost::bind<void>(&HandleStuff::loadLinks, this, _1) ) } } got an error, that the compiler can not deduce a template Argument, but i do not understand what the compiler tries to say. I am new to bind and lambda and i like it a lot, but in some cases the Error-Messages are hard to understand. Thank you for any advice. Please understand, that this example is a reduced Version what is realy going on, so i only give the Functions Interfaces. Simon
