curl_easy_setopt does not seem to have any options to set the POST
content type. So I use something like this:

curl_httppost* post = NULL;
curl_httppost* last = NULL;
curl_slist* upstreamHeaders = NULL;

curl_formadd(&post, &last, CURLFORM_COPYNAME, "src_file",
CURLFORM_FILE, filenameStr_psz, CURLFORM_CONTENTTYPE, mimeType_psz,
CURLFORM_END);

In this case, I am setting the field name to "src_file" and letting
libcurl handle reading and POSTing the file found in filenameStr_psz
using the Content-Type found in mimeType_psz.

In your case, filenameStr_psz will contain the NULL-terminated string
"text/xml".

See: http://curl.haxx.se/libcurl/c/curl_formadd.html

Just make sure you clean up post and last structures using
curl_formfree after you have performed the POST.

HTH.
