Uploading file (non direct) using POST libcurl

Question

Hi want to upload one single input.zip file as well as this xml descrition of file to the server.This is xml description part that I want to send in CURLOPT_POSTFIELDS,

<data_file>
<archive>"true"</archive>
<data_type_id> "42f7710d-9399-45d8-a61f-a018bb6c33f6""</data_type_id>
<data_file_name> "INPUT.zip"</data_file_name>
<description>..</description>
<uploaded>true</uploaded>
<job_id> job_id</job_id>
</data_file>

and this is libcurl part. I'm not sure if we can send both POST parameters and Postform in same request.

    struct curl_httppost *formpost=NULL;
    struct curl_httppost *lastptr=NULL;
    struct curl_slist *headers=NULL;
    static const char buf[] = "Expect:";

    curl_global_init(CURL_GLOBAL_ALL);

     /* Fill in the file upload field */
     curl_formadd(&formpost,
             &lastptr,
             CURLFORM_COPYNAME, "sendfile",
             CURLFORM_FILE, filepathinput.c_str(),
             CURLFORM_END);

     /* Fill in the filename field */
     curl_formadd(&formpost,
             &lastptr,
             CURLFORM_COPYNAME, "INPUT.zip",
             CURLFORM_COPYCONTENTS, filepathinput.c_str(),
             CURLFORM_END);


     /* Fill in the submit field too, even if this is rarely needed */
     curl_formadd(&formpost,
             &lastptr,
             CURLFORM_COPYNAME, "submit",
             CURLFORM_COPYCONTENTS, "send",
             CURLFORM_END);


      curl = curl_easy_init();
       headers = curl_slist_append(headers, buf);
       headers = curl_slist_append(headers, "Content-Type: multipart/form-data");


 if(curl) {

    curl_easy_setopt(curl, CURLOPT_VERBOSE, true);

    curl_easy_setopt(curl, CURLOPT_URL, url);
    curl_easy_setopt(curl, CURLOPT_USERPWD,_loginCBstring.c_str());
    curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
    curl_easy_setopt(curl, CURLOPT_HTTPPOST, formpost);


 curl_easy_setopt(curl, CURLOPT_POSTFIELDS, xmldescription.c_str());
     curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, strlen(xmldescription.c_str()));

    _res = curl_easy_perform(curl);

    if(_res != CURLE_OK)
        fprintf(stderr, "curl_easy_perform() failed: %s\n",
                curl_easy_strerror(_res));

    curl_easy_cleanup(curl);

    curl_formfree(formpost);
    curl_slist_free_all (headers);
}

Thx a lot in advance!
