It isn't extremely obvious in the documentations, but these are the
essentials:

 CURLOPT_POSTFIELDS - point out the data to POST

 CURLOPT_POSTFIELDSIZE - if the data might contain zero bytes this must set
                         the length to post

 CURLOPT_HTTPHEADER - pointed to a linked list of HTTP headers. I quote from
                       the curl_easy_setopt man page:

             Pass a pointer to a linked list of HTTP headers to
             pass to the server in your HTTP request. The linked
             list should be a fully valid list of struct
             curl_slist structs properly filled in. Use
             curl_slist_append(3) to create the list and
             curl_slist_free_all(3) to clean up an entire list.
             If you add a header that is otherwise generated and
             used by libcurl internally, your added one will be
             used instead. If you add a header with no contents
             as in 'Accept:' (no data on the right side of the
             colon), the internally used header will get dis­
             abled. Thus, using this option you can add new head­
             ers, replace internal headers and remove internal
             headers.

... so a "Content-Type: text/xml" header would probably suit your needs.
