Well, something along the lines of this should work (caution: not tested): ptree technologies; /* load xml */ for (ptree::const_iterator iter = technologies.begin(); iter != technologies.end(); ++iter) { std::cout << "ID: " << (*iter).get<std::string>("<xmlattr>.ID") << '\n' } HTH // Johan
Unfortunally this does not work, *iter returns ptree::value_type, so even if I could do std::cout << "ID: " << (*iter).second.get<std::string>("<xmlattr>.ID") << '\n', it will throw "ptree_bad_path" because it can't find the key. It will also throw with get("Technologies.Logistics") and get_child(...).
I said I didn't test it - it required a little tweaking: --- #include <boost/property_tree/ptree.hpp> #include <boost/property_tree/xml_parser.hpp> #include <sstream> #include <iostream> using namespace boost::property_tree; std::stringstream data( "<Technologies>" " <Logistics ID=\"Damage Diagnostics\">" " <DisplayName>Damage Diagnostics</DisplayName>" " <Cost>1500</Cost>" " <Description>Increases repair ability by 10%</Description>" " <RepairAbility>10</RepairAbility>" " <Requires>Advanced Starship Repair</Requires>" " <Category>Logistics</Category>" " <Model>lrgbuilding0</Model>" " <AIValue>30</AIValue>" " </Logistics>" " <Logistics ID=\"Basic Self-Repair\">" " <DisplayName>Basic Self-Repair</DisplayName>" " <Cost>3000</Cost>" " <Description>Increases repair ability by 10%</Description>" " <RepairAbility>10</RepairAbility>" " <Requires>Damage Diagnostics</Requires>" " <Category>Logistics</Category>" " <Model>controlgrav0</Model>" " <AIValue>40</AIValue>" " </Logistics>" "</Technologies>"); ptree pt; read_xml(data, pt); ptree technologies = pt.get_child("Technologies"); for (ptree::const_iterator iter = technologies.begin(); iter != technologies.end(); ++iter) { std::string const & name = (*iter).first; ptree const& logistics = (*iter).second; std::cout << name << ": ID = " << logistics.get<std::string>("<xmlattr>.ID") << '\n'; } --- // Johan
