Title Body

I am sorry, I asked a question about the same topic before, but my problem concerns another aspect of the one described there ( How to iterate a boost... ). Take a look at the following code: #include <iostream> #include <string> #include <boost/property_tree/ptree.hpp> #include <boost/property_tree/xml_parser.hpp> #include <boost/algorithm/string/trim.hpp> int main(int argc, char** argv) { using boost::property_tree::ptree; ptree pt; read_xml("try.xml", pt); ptree::const_iterator end = pt.end(); for (ptree::const_iterator it = pt.begin(); it != end; it++) std::cout << "Here " << it->? << std::endl; } Well, as I got told told in the question I mentioned, there is the possibility to use iterators on property_tree in Boost, but I do not know what type it is, and what methods or properties I can use. Well, I assume that it must be another ptree or something representing another xml hierarchy to be browsed again (if I want) but documentation about this is very bad. I do not know why, but in boost docs I cannot find nothing good, just something about a macro to browse nodes, but this approach is one I would really like to avoid. So getting to my question here: Once getting the iterator on a ptree , how can I access node name, value, parameters (a node in a xml file)? Thankyou
