Victor,

I have recently come across the same problem.  Microsoft supplied a very
nice method to submit xml files in asp.  Unfortunately, it is harder to
implement in PHP.  The script below is what I eventually came up with,
and it works for me.  Don't know if it applies to your situation
exactly, but hope it helps at any rate.

Cheers,

$xmlRequest = "<request>\n";
$xmlRequest.= "\t<contents>foo</contents>\n";
$xmlRequest.= "</request>";

$url = "http://www.wherever.com";;
$port = "83";
$path = "/path/to/script.asp"

/*
*	$errno and $errstr are blank, see the docs for fsockopen
*/

$sockXml = fsockopen($url, $port, $errno, $errstr, 30);

if (!$sockXml) {
   echo $errstr." (".$errno.")<br />\n";
} else {
/*
* 	http headers
*/
 	$out = "POST ".$path." HTTP/1.1\n";
	$out .= "Host: www.wherever.com:83\n";
	$out .= "Content-Type: application/x-www-form-urlencoded\n"; 
	$out .= "Content-Length: ".strlen($xmlRequest)."\n"; 
	$out .= "Connection: Close\n";
	$out .= "\n".$xmlRequest; 
	$out .= "\n" ;

/*
* 	write the http headers to the open socket
*/	
   fwrite($sockXml, $out);

/*
*	get the results back
*/
   $strReturned = "";
   while (!feof($sockXml)) {
   		$strReturned.= @fgets($sockXml, 4096);
   }
   echo $strReturned."\n";
