no table rows found

ok, problem you're doing head request. line does: curl_setopt($ch, curlopt_nobody, 1); (basically removes body). also, later on in file call curl_setopt($ch, curlopt_header, 1);, returns headers server returns. looking @ code, looks want xml uri you're requesting, not headers. remove 2 lines , should xml you're expecting
