boost-propertytree

问题 I would like to share with you an issue I'm having while trying to process some attributes from XML elements in C++ with Boost libraries (version 1.52.0). Given the following code: #define ATTR_SET ".<xmlattr>" #define XML_PATH1 "./pets.xml" #include <iostream> #include <string> #include <boost/foreach.hpp> #include <boost/property_tree/ptree.hpp> #include <boost/property_tree/xml_parser.hpp> using namespace std; using namespace boost; using namespace boost::property_tree; const ptree& empty

问题 I am using boost/property_tree to create an XML file. Unfortunately I cannot figure out how to add xml-stylesheet processing instructions to the file. Desirable output: <?xml version="1.0" encoding="utf-8"?> <-- This is added automatically <?xml-stylesheet type="text/xsl" href="report.xsl"?> <-- How to add this line <report> ... </report> Is that possible with boost/property_tree/ptree? 回答1: It appears that boost/property_tree xml writer doesn't have a support for xml stylesheets processing

问题 I have a INI file like [Section1] Value1 = /home/%USER%/Desktop Value2 = /home/%USER%/%SOME_ENV%/Test and want to parse it using Boost. I tried using Boost property_tree like boost::property_tree::ptree pt; boost::property_tree::ini_parser::read_ini("config.ini", pt); std::cout << pt.get<std::string>("Section1.Value1") << std::endl; std::cout << pt.get<std::string>("Section1.Value2") << std::endl; But it didn't expand the environment variable. Output looks like /home/%USER%/Desktop /home/

问题 I'm using boost::property_tree to read and write XML configuration files in my application. But when I write the file the output looks kind of ugly with lots of empty lines in the file. The problem is that it's supposed to be edited by humans too so I'd like to get a better output. As an example I wrote a small test program : #include <boost/property_tree/ptree.hpp> #include <boost/property_tree/xml_parser.hpp> int main( void ) { using boost::property_tree::ptree; ptree pt; // reading file

问题 I'm trying to serialize using boost property tree write_json, it saves everything as strings, it's not that data are wrong, but I need to cast them explicitly every time and I want to use them somewhere else. (like in python or other C++ json (non boost) library) here is some sample code and what I get depending on locale: boost::property_tree::ptree root, arr, elem1, elem2; elem1.put<int>("key0", 0); elem1.put<bool>("key1", true); elem2.put<float>("key2", 2.2f); elem2.put<double>("key3", 3.3
