iPhone Web Service NSData and PHP

I'm fairly new to iOS development and want to send a request message to a web service that I created in PHP. It will take the XML request, process and then provide a response XML message.

However, the issue I'm having is that when sending data to the Webservice it is in NSData form.

NSLog of the data being sent is:

<3c3f786d 6c207665 7273696f etc etc ... 743e>

However the PHP script is expecting an XML message like this:

<?xml version="1.0" ?><request-message><tag-1></tag-1><tag-2></tag-2></request-message>

So my question is, is there a way of sending the XML without converting to data, or is there a way to convert the NSData string to readable XML on the PHP Server Side?

Thanks in advance.

EDIT: To include request code:

// Construct the webservice URL
NSURL *url = [NSURL URLWithString:@"http://localhost/web/check_data.php"];

NSString *requestXML = @"<?xml version='1.0'?><request-message><tag-1>VALUE1</tag-1><tag-2>VALUE2</tag-2></request-message>";

NSData *data = [requestXML dataUsingEncoding:NSUTF8StringEncoding];

// Create a request object with that URL
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:30];

[request setHTTPBody:data];
[request setHTTPMethod:@"POST"];

Send the XML on the HTTP Body and parse it in the PHP side and you need to set the Content-Type To application/xml; charset=utf-8:

NSString* sXMLToPost = @"<?xml version=\"1.0\" ?><request-message><tag-1></tag-1><tag-2></tag-2></request-message>";

NSData* data = [sXMLToPost dataUsingEncoding:NSUTF8StringEncoding];

NSURL *url = [NSURL URLWithString:@"http://myurl.com/RequestHandler.ashx"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];

[request setHTTPMethod:@"POST"];
[request setValue:@"application/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:[sXMLToPost dataUsingEncoding:NSUTF8StringEncoding]];

NSURLResponse *response;
NSError *error;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];

if (error) {..handle the error}

and on the server try the following PHP code:

$handle = fopen("php://input", "rb");
$http_raw_post_data = '';
while (!feof($handle)) {
    $http_raw_post_data .= fread($handle, 8192);
}
fclose($handle);

Have a look at this iPhone sending POST with NSURLConnection
