xml - how to make boost property tree print all subtrees and then end parent tree -
in code below iam trying traverse through nested map , not sure how property tree interpreting data.
it printing parent tree data , starts printing child tree

thanks tejas
trees contain subtrees. printing parent tree is printing subtrees before closing parent.
both current output , "intended" output invalid documents (there can 1 root element).
you'll need put data single tree, e.g.:
ptree pt; auto& root = pt.add_child("root", ptree{}); auto& list = root.add_child("list", ptree{}); auto& assetlist = root.add_child("assetlist", ptree{}); which prints following document:
<?xml version="1.0" encoding="utf-8"?> <root> <list> <groupid>1</groupid> <grouptype>et</grouptype> <groupid>1</groupid> <grouptype>pt</grouptype> <groupid>2</groupid> <grouptype>et</grouptype> <groupid>2</groupid> <grouptype>pt</grouptype> <groupid>3</groupid> <grouptype>et</grouptype> <groupid>3</groupid> <grouptype>pt</grouptype> </list> <assetlist> <assetid>780254</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780255</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780256</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780254</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780255</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780256</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780254</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780255</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780256</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780254</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780255</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780256</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780254</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780255</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780256</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780254</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780255</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> <assetid>780256</assetid> <milepost>milepost</milepost> <dummy>dummyval</dummy> </assetlist> </root> which well-formed xml :)

if want group asset lists grouptypes, .... need write code that?
ptree pt; auto& list = pt.add_child("list", ptree{}); //create set of types firstly std::set<std::string> types { "et", "pt" }; typedef std::map<std::string,values> mywsdata; typedef std::map< std::string , std::set<mywsdata> > myfinaldata; typedef std::map< int,std::set<myfinaldata> > mygroupdata; values a,b,c; mywsdata et_data1 { { "780256", }, { "780255", b }, { "780254", c } }, pt_data2 = et_data1; std::set<mywsdata> myet_pt_data { et_data1, pt_data2 }; myfinaldata fd , fd1 = fd, fd2 = fd; std::set<myfinaldata> mfd { { { "et", myet_pt_data }, { "pt", myet_pt_data } }, { { "et", myet_pt_data }, { "pt", myet_pt_data } }, { { "et", myet_pt_data }, { "pt", myet_pt_data } } }; mfd.insert(fd); mfd.insert(fd1); mfd.insert(fd2); mygroupdata mygd; mygd.insert(std::make_pair (1,mfd) ); mygd.insert(std::make_pair (2,mfd) ); mygd.insert(std::make_pair (3,mfd) ); (auto &a : mygd) { for(auto &b:a.second) //get std::set { for(auto &the_map:b) //get map set { auto& group = list.add_child("group", {}); group.add("<xmlattr>.groupid", a.first); group.add("grouptype",the_map.first); auto& assetlist = group.add_child("assetlist", ptree{}); for(auto &the_set:the_map.second) { // the_map takes values set // the_map actual type std::map<std::string,values>& (const auto& the_map : the_set) { // the_value takes value of current map (the_map) // the_value actual type std::pair<std::string,values>& assetlist.add("assetid",the_map.first); assetlist.add("milepost",the_map.second.a); assetlist.add("dummy",the_map.second.b); // assetlist.add("value", map.first) // .add("<xmlattr>.active", true); } } } } } xml_parser::write_xml(std::cout, pt); prints:
