Read Write XML File In C++ [closed]

Answer 1

I recommend MSXML. It may look complicated, but it's nice and easy when you get used to it.
Here's a sample:

input.xml:

    
        FL
        FR
        RL
        RR
    

code:

#include 
#include 
#include 
#import  rename_namespace(_T("MSXML"))

int main(int argc, char* argv[]) {
    HRESULT hr = CoInitialize(NULL); 
    if (SUCCEEDED(hr)) {
        try {
            MSXML::IXMLDOMDocument2Ptr xmlDoc;
            hr = xmlDoc.CreateInstance(__uuidof(MSXML::DOMDocument60),
                                       NULL, CLSCTX_INPROC_SERVER);
            // TODO: if (FAILED(hr))...

            if (xmlDoc->load(_T("input.xml")) != VARIANT_TRUE) {
                printf("Unable to load input.xml\n");
            } else {
                printf("XML was successfully loaded\n");

                xmlDoc->setProperty("SelectionLanguage", "XPath");
                MSXML::IXMLDOMNodeListPtr wheels = xmlDoc->selectNodes("/Car/Wheels/*");
                printf("Car has %u wheels\n", wheels->Getlength());

                MSXML::IXMLDOMNodePtr node;
                node = xmlDoc->createNode(MSXML::NODE_ELEMENT, _T("Engine"), _T(""));
                node->text = _T("Engine 1.0");
                xmlDoc->documentElement->appendChild(node);
                hr = xmlDoc->save(_T("output.xml"));
                if (SUCCEEDED(hr))
                    printf("output.xml successfully saved\n");
            }
        } catch (_com_error &e) {
            printf("ERROR: %ws\n", e.ErrorMessage());
        }
        CoUninitialize();
    }
    return 0;
}

output: XML was successfully loaded Car has 4 wheels output.xml successfully saved

output.xml:

    
        1
        2
        3
        4
    
    Engine 1.0
