Using Boost to read and write XML files

Question

Is there any good way (and a simple way too) using Boost to read and write XML files?

I can\'t seem to find any simple sample to read XML files using Boost. Can you

There is an easy way to read XML with BOOST. This example is with std::wstring:

#include  
#include 
#include 
#include 

bool CMyClass::ReadXML(std::wstring &full_path)
{
    using boost::property_tree::wptree;

    // Populate tree structure pt:
    wptree pt;
    std::wstringstream ss; ss << load_text_file(full_path); // See below for ref.
    read_xml(ss, pt);

    // Traverse pt:
    BOOST_FOREACH(wptree::value_type const& v, pt.get_child(L"Settings"))
    {
        if (v.first == L"GroupA")
        {
            unsigned int n1 = v.second.get(L"One");
            unsigned int n2 = v.second.get(L"Two");
            unsigned int n3= v.second.get(L"Three");
        }
        else if (v.first == L"GroupB")
        {
            std::wstring wstrA = v.second.get(L"A");
            std::wstring wstrB = v.second.get(L"B");
        }
    };
}

To read attributes is just a little bit more complicated.

Just for the reference:

std::wstring load_text_file(std::wstring &full_path)
{
    std::wifstream wif(full_path);

    wif.seekg(0, std::ios::end);
    buffer.resize(wif.tellg());
    wif.seekg(0);
    wif.read(buffer.data(), buffer.size());

    return buffer;
}
