Use boost: property_tree to generate xml with attribute, boostproperty_tree
I have previously written an article "using Boost property tree to parse xml with attribute", but my sister-in-law has never posted this article. It's almost three years since I posted the previous article. It's so fast.
This is the next article. Use boost: property_tree to generate xml with attribute.

View the demo code directly:

#include <iostream>#include <sstream>#include <boost/property_tree/xml_parser.hpp>using namespace std;int main(){using boost::property_tree::ptree;    ptree pt;    ptree tab1;    ptree tab2;    tab1.put("attr1", "value1");    tab1.put("attr1.<xmlattr>.code", "ABC");    tab1.put("attr2", "value2");    tab2.put("attr3", "value3");    tab2.put("attr3.<xmlattr>.code", "XYZ");    ptree array;    auto& a = array.add_child("table1", tab1);    a.put("<xmlattr>.tabid", "1");    auto& b = array.add_child("table2", tab2);    b.put("<xmlattr>.tabid", "2");    pt.put_child("demoxml", array);    ostringstream oss;         write_xml(oss, pt, xml_writer_settings<char>(' ', 2));    cout << oss.str() << endl;        return 0;}

The generated xml is as follows:

<?xml version="1.0" encoding="utf-8"?><demoxml>  <table1 tabid="1">    <attr1 code="ABC">value1</attr1>    <attr2>value2</attr2>  </table1>  <table2 tabid="2">    <attr3 code="XYZ">value3</attr3>  </table2></demoxml>

How to parse multi-layer xml using boost property_tree, such as <a> <B> <c> 11 </c> </B> <c> 22 </c> </B>

Std: vector

The first parameter of the read_xml function reading xml in the boost library does not support the Chinese path?

Actually, boost uses STL streaming internally.

Sometimes, opening a file with a Chinese path using ifstream or ofstream fails.

Solution:
1. Use C language functions to set the Chinese Runtime Environment
Setlocale (LC_ALL, "Chinese-simplified ");

2. Use STL functions to set the environment for the System Language
Std: locale: global (std: locale (""));

Of course, select 2!
