C++通过msxml调用webservice示例分享

  //sb.append("");//调用HelloWorld函数

  sb.append("");
  sb.append("colin");//调用SayHello函数，参数名是name，值为colin
  sb.append("");

  sb.append("");
  sb.append("");

  xmlrequest->send(_variant_t(sb.c_str()));//发道数据

        BSTR bstrbody;
        xmlrequest->get_responseText(&bstrbody);//得到返回数据
        _bstr_t bstrtbody(bstrbody);
        printf("%s\n",(LPCTSTR)bstrtbody);
        MSXML2::IXMLDOMDocument2Ptr m_xmldoc;
        m_xmldoc.CreateInstance(__uuidof(MSXML2::DOMDocument));
        m_xmldoc->loadXML(bstrbody);
        MSXML2::IXMLDOMNodePtr node = m_xmldoc->documentElement->firstChild;

        LPCTSTR str = (LPCTSTR)node->nodeName;
        string str2=(string)m_xmldoc->documentElement->text;
        cout<    }
    catch (_com_error &e)
    {
        printf("Description = '%s'\n", (char*) e.Description());
    }
    CoUninitialize();
    printf("program end\n");
    return 0;
}
