Boost Property_Tree iterators, how to handle them?
- by Andry
Hello... I am sorry but I asked a question about the same argument before, but my problem concerns another aspect of the one described in that question (How to iterate a boost...).
My problem is this, 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 told me in the previous question, 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 about this... just something about a macro to browse nodes, but this approach is one I would really like to avoid...
Well, the question is so...
Once getting the iterator on a ptree, how can I access node name, value, parameters (a node in a xml file)?
Thankyou
