Demonstrates how to call PostXml to call a SOAP web service. C++

void ChilkatSample(void)
    {
    bool success = false;

    //  This example requires the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    //  --------------------------------------------------------------------------------
    //  Also see Chilkat's Online WSDL Code Generator
    //  to generate code and SOAP Request and Response XML for each operation in a WSDL.
    //  --------------------------------------------------------------------------------

    //  This example uses a live web service at:
    //  http://www.webservicex.net/uklocation.asmx
    //  It gets the UK town,Postcode and County by Postcode(First Section of Post Code)

    //  The SOAP XML will look like this:
    //  <?xml version="1.0" encoding="utf-8"?>
    //  <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    //    <soap:Body>
    //      <GetUKLocationByPostCode xmlns="http://www.webserviceX.NET">
    //        <PostCode>string</PostCode>
    //      </GetUKLocationByPostCode>
    //    </soap:Body>
    //  </soap:Envelope>

    //  For this example's sake, we'll load the XML from a file.  We'll test using PostCode "E3".  
    //  The SOAP XML for this example may be downloaded from:
    //  http://www.chilkatsoft.com/testData/ukPostCodeSoap.xml
    CkXml xml;
    success = xml.LoadXmlFile("ukPostCodeSoap.xml");
    if (success == false) {
        std::cout << xml.lastErrorText() << "\r\n";
        return;
    }

    const char *strXml = xml.getXml();

    int responseStatusCode;
    CkHttp http;

    //  We'll need to add this in the HTTP header:
    //  SOAPAction: "http://www.webserviceX.NET/GetUKLocationByPostCode"
    http.SetRequestHeader("SOAPAction","http://www.webserviceX.NET/GetUKLocationByPostCode");

    //  The endpoint for this soap service is:
    const char *endPoint = "http://www.webservicex.net/uklocation.asmx";

    //  Note: This particular web service was live and functioning at the time this example
    //  was written.  It is possible that as time progresses, this web service will no longer
    //  be availble...
    CkHttpResponse resp;
    success = http.HttpStr("POST",endPoint,strXml,"utf-8","text/xml",resp);
    if (success == false) {
        std::cout << http.lastErrorText() << "\r\n";
        return;
    }

    responseStatusCode = resp.get_StatusCode();
    //  You may wish to verify that the responseStatusCode equals 200...
    std::cout << "Response Status Code: " << responseStatusCode << "\r\n";

    //  You may examine the exact HTTP header sent with the POST like this:
    std::cout << "LastHeader:" << "\r\n";
    std::cout << http.lastHeader() << "\r\n";

    //  Examine the XML returned by the web service:
    std::cout << "XML Response:" << "\r\n";
    CkXml xmlResp;
    xmlResp.LoadXml(resp.bodyStr());
    std::cout << xmlResp.getXml() << "\r\n";
